+About NSPR
+==========
+
+NetScape Portable Runtime (NSPR) provides platform independence for
+non-GUI operating system facilities. These facilities include threads,
+thread synchronization, normal file and network I/O, interval timing and
+calendar time, basic memory management (malloc and free) and shared
+library linking.
+
+History
+~~~~~~~
+
+A good portion of the library's purpose, and perhaps the primary purpose
+in the Gromit environment, was to provide the underpinnings of the Java
+VM, more or less mapping the *sys layer* that Sun defined for the
+porting of the Java VM to various platforms. NSPR went beyond that
+requirement in some areas and since it was also the platform independent
+layer for most of the servers produced by Netscape. It was expected and
+preferred that existing code be restructured and perhaps even rewritten
+in order to use the NSPR API. It is not a goal to provide a platform for
+the porting into Netscape of externally developed code.
+
+At the time of writing the current generation of NSPR was known as
+NSPR20. The first generation of NSPR was originally conceived just to
+satisfy the requirements of porting Java to various host environments.
+NSPR20, an effort started in 1996, built on that original idea, though
+very little is left of the original code. (The "20" in "NSPR20" does not
+mean "version 2.0" but rather "second generation".) Many of the concepts
+have been reformed, expanded, and matured. Today NSPR may still be
+appropriate as the platform dependent layer under Java, but its primary
+application is supporting clients written entirely in C or C++.
+
+.. _How_It_Works:
+
+How It Works
+~~~~~~~~~~~~
+
+NSPR's goal is to provide uniform service over a wide range of operating
+system environments. It strives to not export the *lowest common
+denominator*, but to exploit the best features of each operating system
+on which it runs, and still provide a uniform service across a wide
+range of host offerings.
+
+Threads
+^^^^^^^
+
+Threads are the major feature of NSPR. The industry's offering of
+threads is quite sundry. NSPR, while far from perfect, does provide a
+single API to which clients may program and expect reasonably consistent
+behavior. The operating systems provide everything from no concept of
+threading at all up to and including sophisticated, scalable and
+efficient implementations. NSPR makes as much use of what the systems
+offer as it can. It is a goal of NSPR that NSPR impose as little
+overhead as possible in accessing those appropriate system features.
+
+.. _Thread_synchronization:
+
+Thread synchronization
+^^^^^^^^^^^^^^^^^^^^^^
+
+Thread synchronization is loosely based on Monitors as described by
+C.A.R. Hoare in *Monitors: An operating system structuring concept* ,
+Communications of the ACM, 17(10), October 1974 and then formalized by
+Xerox' Mesa programming language ("Mesa Language Manual", J.G. Mitchell
+et al, Xerox PARC, CSL-79-3 (Apr 1979)). This mechanism provides the
+basic mutual exclusion (mutex) and thread notification facilities
+(condition variables) implemented by NSPR. Additionally, NSPR provides
+synchronization methods more suited for use by Java. The Java-like
+facilities include monitor *reentrancy*, implicit and tightly bound
+notification capabilities with the ability to associate the
+synchronization objects dynamically.
+
+.. _I.2FO:
+
+I/O
+^^^
+
+NSPR's I/O is a slightly augmented BSD sockets model that allows
+arbitrary layering. It was originally intended to export synchronous I/O
+methods only, relying on threads to provide the concurrency needed for
+complex applications. That method of operation is preferred though it is
+possible to configure the network I/O channels as *non-blocking* in the
+traditional sense.
+
+.. _Network_addresses:
+
+Network addresses
+^^^^^^^^^^^^^^^^^
+
+Part of NSPR deals with manipulation of network addresses. NSPR defines
+a network address object that is Internet Protocol (IP) centric. While
+the object is not declared as opaque, the API provides methods that
+allow and encourage clients to treat the addresses as polymorphic items.
+The goal in this area is to provide a migration path between IPv4 and
+IPv6. To that end it is possible to perform translations of ASCII
+strings (DNS names) into NSPR's network address structures, with no
+regard to whether the addressing technology is IPv4 or IPv6.
+
+Time
+^^^^
+
+Timing facilities are available in two forms: interval timing and
+calendar functions.
+
+Interval timers are based on a free running, 32-bit, platform dependent
+resolution timer. Such timers are normally used to specify timeouts on
+I/O, waiting on condition variables and other rudimentary thread
+scheduling. Since these timers have finite namespace and are free
+running, they can wrap at any time. NSPR does not provide an *epoch* ,
+but expects clients to deal with that issue. The *granularity* of the
+timers is guaranteed to be between 10 microseconds and 1 millisecond.
+This allows a minimal timer *period* in of approximately 12 hours. But
+in order to deal with the wrap-around issue, only half that namespace
+may be utilized. Therefore, the minimal usable interval available from
+the timers is slightly less than six hours.
+
+Calendar times are 64-bit signed numbers with units of microseconds. The
+*epoch* for calendar times is midnight, January 1, 1970, Greenwich Mean
+Time. Negative times extend to times before 1970, and positive numbers
+forward. Use of 64 bits allows a representation of times approximately
+in the range of -30000 to the year 30000. There is a structural
+representation (*i.e., exploded* view), routines to acquire the current
+time from the host system, and convert them to and from the 64-bit and
+structural representation. Additionally there are routines to convert to
+and from most well-known forms of ASCII into the 64-bit NSPR
+representation.
+
+.. _Memory_management:
+
+Memory management
+^^^^^^^^^^^^^^^^^
+
+NSPR provides API to perform the basic malloc, calloc, realloc and free
+functions. Depending on the platform, the functions may be implemented
+almost entirely in the NSPR runtime or simply shims that call
+immediately into the host operating system's offerings.
+
+Linking
+^^^^^^^
+
+Support for linking (shared library loading and unloading) is part of
+NSPR's feature set. In most cases this is simply a smoothing over of the
+facilities offered by the various platform providers.
+
+Where It's Headed
+~~~~~~~~~~~~~~~~~
+
+NSPR is applicable as a platform on which to write threaded applications
+that need to be ported to multiple platforms.
+
+NSPR is functionally complete and has entered a mode of sustaining
+engineering. As operating system vendors issue new releases of their
+operating systems, NSPR will be moved forward to these new releases by
+interested players.

+Creating a cookie log
+=====================
+
+Creating a cookie log is often necessary to troubleshoot problems with
+Firefox's cookie handling. If you are reading this, you have probably
+been directed here from a bug report. Please follow the instructions
+below to run Firefox with cookie logging enabled.
+
+.. _Enabling_Cookie_Logging:
+
+Enabling Cookie Logging
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Windows
+^^^^^^^
+
+Open a command prompt (this is under Programs or Programs/Accessories in
+normal installations of Windows).
+
+#. Change to your Firefox directory (usually C:\Program Files\Mozilla
+ Firefox)
+#. Type "set NSPR_LOG_FILE=C:\temp\cookie-log.txt", enter
+#. Type "set NSPR_LOG_MODULES=cookie:4" and press Enter
+#. Run Firefox by typing "firefox.exe" and pressing Enter.
+
+Linux
+^^^^^
+
+Start a command shell (these instructions are for bash, if you use
+something else, you probably know how to modify these instructions
+already).
+
+#. Change to the installation directory for Firefox.
+#. Type "export NSPR_LOG_FILE=~/cookie-log.txt" and press Enter.
+#. Type "export NSPR_LOG_MODULES=cookie:4" and press Enter.
+#. Run Firefox by typing "./firefox" and pressing Enter
+
+Mac OS X
+^^^^^^^^
+
+Open Terminal.app, which is located in the /Applications/Utilities
+folder (these instructions are for bash, the default shell in Mac OS X
+10.3 and higher; if you use something else, you probably know how to
+modify these instructions already).
+
+#. Change to the installation directory for Firefox, e.g. type "cd
+ /Applications/Firefox.app/Contents/MacOS" and press Return.
+#. Type "export NSPR_LOG_FILE=~/Desktop/cookie-log.txt" and press
+ Return.
+#. Type "export NSPR_LOG_MODULES=cookie:4" and press Return.
+#. Run Firefox by typing "./firefox-bin" and pressing Return (note that
+ Firefox will launch behind windows for other applications).
+
+Creating the Log
+~~~~~~~~~~~~~~~~
+
+Now that you have Firefox running with logging enabled, please try to
+replicate the bug using the steps to reproduce from the bug report. Once
+you have reproduced the bug, shut down Firefox. Close out of the command
+prompt/shell/Terminal, and then launch Firefox normally. Finally, attach
+the cookie-log.txt file to the bug where it was requested (by clicking
+on Create New Attachment). It should be in C:\temp on Windows, your home
+directory on Linux, or the Desktop on Mac OS X.
+
+Thanks for helping us make Firefox better!

+PR_Poll() and the layered I/O
+=============================
+
+*[last edited by AOF 8 August 1998]*
+This memo discusses some of the nuances of using PR_Poll() in
+conjunction with *layered I/O*. This is a relatively new feature in NSPR
+2.0, not that it hasn't been in the source tree for a while, but in that
+it has had no clients.
+
+Implementation
+--------------
+
+NSPR provides a public API function, PR_Poll() that is modeled after
+UNIX' ``poll()`` system call.
+
+The implementation of :ref:`PR_Poll` is somewhat complicated. Not only
+does it map the :ref:`PRPollDesc` array into structures needed by the
+underlying OS, it also must deal with layered I/O. This is done despite
+the fact that :ref:`PR_Poll` itself is *not* layered. For every element
+of the :ref:`PRPollDesc` array that has a non-NULL :ref:`PRFileDesc` and whose
+``in_flags`` are not zero, it calls the file descriptor's
+``poll() method``.
+The ``poll()`` method is one of the vector contained in the
+:ref:`PRIOMethods` table. In the case of layered I/O, the elements (the
+methods) of the methods table may be overridden by the implementor of
+that layer. The layers are then *stacked.* I/O using that *stack* will
+call through the method at the top layer, and each layer may make
+altering decisions regarding how the I/O operation should proceed.
+
+The purpose of the ``poll()`` method is to allow a layer to modify the
+flags that will ultimately be used in the call to the underlying OS'
+``poll()`` (or equivalent) function. Such modification might be useful
+if one was implementing an augmented stream protocol (*e.g.,* **SSL**).
+SSL stands for **Secure Socket Layer**, hence the obvious applicability
+as an example. But it is way to complicated to describe in this memo, so
+this memo will use a much simpler layered protocol.
+The example protocol is one that, in order to send *n* bytes, it must
+first ask the connection's peer if the peer is willing to receive that
+many bytes. The form of the request is 4 bytes (binary) stating the
+number of bytes the sender wishes to transmit. The peer will send back
+the number of bytes it is willing to receive (in the test code there are
+no error conditions, so don't even ask).
+
+The implication of the protocol is obvious. In order to do a
+:ref:`PR_Send` operation, the layer must first do a *different* send and
+then *receive* a response. Doing this and keeping the *stack's* client
+unaware is the goal. **It is not a goal of NSPR 2.0 to hide the nuances
+of synchronous verses non-blocking I/O**.
+
+The layered methods
+-------------------
+
+Each layer must implement a suitable function for *every* element of the
+methods table. One can get a copy of default methods by calling
+:ref:`PR_GetDefaultIOMethods` These methods simply pass all calls
+through the layer on to the next lower layer of the stack.
+
+A layer implementor might copy the elements of the ``PRIOMethods``
+acquired from this function into a methods table of its own, then
+override just those methods of interest. *Usually* (with only a single
+exception) a layered method will perform its design duties and then call
+the next lower layer's equivalent function.
+
+Layered ``poll()``
+------------------
+
+One of the more interesting methods is the ``poll()``. It is called by
+the runtime whenever the client calls :ref:`PR_Poll`. It may be called at
+the *top* layer for *every* file descriptor in the poll descriptor. It
+may be called zero or more times. The purpose of the ``poll()`` method
+is to provide the layer an opportunity to adjust the polling bits as
+needed. For instance, if a client (*i.e.*, top layer) is calling
+:ref:`PR_Poll` for a particular file descriptor with a *read* poll
+request, a lower layer might decide that it must perform a *write*
+first.
+In that case, the layer's ``poll()`` method would be called with
+**``in_flags``** including a ``PR_POLL_READ`` flag. However, the
+``poll()`` method would call the next lower layer's ``poll()`` method
+with a ``PR_POLL_WRITE`` bit set. This process of re-assigning the poll
+flags can happen as many times as there are layers in the stack. It is
+the final value, the one returned to the caller of the top layer's
+``poll()`` method (:ref:`PR_Poll`) that will be used by the runtime when
+calling the OS' ``poll()`` (or equivalent) system call.
+
+It is expected that the modification of the polling bits propagate from
+the top of the stack down, allowing the layer closest to the bottom of
+the stack to provide the final setting. The implication is that there
+should be no modifications of the **``in_flags``** during the *return*
+phase of the layered function.
+
+For example:
+
+It is not advised to modify the ``final_in_flags`` between the call to
+the lower layer's ``poll()`` method and the ``return`` statement.
+The third argument of the ``poll()`` method is a pointer to a 16-bit
+word. If the layer sets a value in memory through that pointer *and*
+returns with a value that has *corresponding* bits, the runtime assumes
+that the file descriptor is ready immediately.
+
+There are two important deviations from the normal. First, this is the
+one (known) exception to having a layered routine call the stack's next
+lower layer method. If bits are set in the ``out_flags`` the method
+should return *directly*. Second, the runtime will observe that the
+layer claims this file descriptor is ready and suppress the call to the
+OS' ``poll()`` system call.
+
+At this time the only known use for this feature is to allow a layer to
+indicate it has buffered *input*. Note that it is not appropriate for
+buffered *output* since in order to write/send output the runtime must
+still confirm with the OS that such an operation is permitted.
+
+Since the ``poll()`` method may be called zero or more times it must
+therefore be *idempotent* or at least *functional*. It will need to look
+at the layer's state, but must not make modifications to that state that
+would cause subsequent calls within the same :ref:`PR_Poll` call to
+return a different answer. Since the ``poll()`` method may not be called
+at all, so there is not guarantee that any modifications that would have
+been performed by the routine will every happen.

+Nonblocking IO in NSPR
+======================
+
+
+Introduction
+------------
+
+Previously, all I/O in the NetScape Portable Runtime (NSPR) was
+*blocking* (or *synchronous*). A thread invoking an io function is
+blocked until the io operation is finished. The blocking io model
+encourages the use of multiple threads as a programming model. A thread
+is typically created to attend to one of the simultaneous I/O operations
+that may potentially block.
+
+In the *nonblocking* io model, a file descriptor may be marked as
+nonblocking. An io function on a nonblocking file descriptor either
+succeeds immediately or fails immediately with
+<tt>PR_WOULD_BLOCK_ERROR</tt>. A single thread is sufficient to attend
+to multiple nonblocking file descriptors simultaneously. Typically, this
+central thread invokes <tt>PR_Poll()</tt> on a set of nonblocking file
+descriptors. (Note: <tt>PR_Poll()</tt> also works with blocking file
+descriptors, although it is less useful in the blocking io model.) When
+<tt>PR_Poll()</tt> reports that a file descriptor is ready for some io
+operation, the central thread invokes that io function on the file
+descriptor.
+
+.. _Creating_a_Nonblocking_Socket:
+
+Creating a Nonblocking Socket
+-----------------------------
+
+*Only sockets can be made nonblocking*. Regular files always operate in
+blocking mode. This is not a serious constraint as one can assume that
+disk I/O never blocks. Fundamentally, this constraint is due to the fact
+that nonblocking I/O and <tt>select()</tt> are only available to sockets
+on some platforms (e.g., Winsock).
+
+In NSPR, a new socket returned by <tt>PR_NewTCPSocket()</tt> or
+<tt>PR_NewUDPSocket()</tt> is always created in blocking mode. One can
+make the new socket nonblocking by using <tt>PR_SetSockOpt()</tt> as in
+the example below (error checking is omitted for clarity):
+
+|
+| <tt>PRFileDesc \*sock;</tt>
+| **<tt>PRIntn optval = 1;</tt>**
+
+<tt>sock = PR_NewTCPSocket();</tt>
+
+::
+
+ /*
+ * Make the socket nonblocking
+ */
+
+ PR_SetSockOpt(sock, PR_SockOpt_Nonblocking, &optval, sizeof(optval));
+
+.. _Programming_Constraints:
+
+Programming Constraints
+-----------------------
+
+There are some constraints due to the use of NT asynchronous I/O in the
+NSPR. In NSPR, blocking sockets on NT are associated with an I/O
+completion port. Once associated with an I/O completion port, we can't
+disassociate the socket from the I/O completion port. I have seen some
+strange problems with using a nonblocking socket associated with an I/O
+completion port. So the first constraint is:
+
+ **The blocking/nonblocking io mode of a new socket is committed the
+ first time a potentially-blocking io function is invoked on the
+ socket. Once the io mode of a socket is committed, it cannot be
+ changed.**
+
+The potentially-blocking io functions include <tt>PR_Connect()</tt>,
+<tt>PR_Accept()</tt>, <tt>PR_AcceptRead()</tt>, <tt>PR_Read()</tt>,
+<tt>PR_Write()</tt>, <tt>PR_Writev()</tt>, <tt>PR_Recv()</tt>,
+<tt>PR_Send()</tt>, <tt>PR_RecvFrom()</tt>, <tt>PR_SendTo()</tt>, and
+<tt>PR_TransmitFile(),</tt> and do not include <tt>PR_Bind()</tt> and
+<tt>PR_Listen()</tt>.
+
+In blocking mode, any of these potentially-blocking functions requires
+the use of the NT I/O completion port. So at that point we must
+determine whether to associate the socket with the I/O completion or
+not, and that decision cannot be changed later.
+
+There is a second constraint, due to the use of NT asynchronous I/O and
+the recycling of used sockets:
+
+ **The new socket returned by <tt>PR_Accept()</tt> or
+ <tt>PR_AcceptRead()</tt> inherits the blocking/nonblocking io mode of
+ the listening socket and this cannot be changed.**
+
+The socket returned by <tt>PR_Accept()</tt> or <tt>PR_AcceptRead()</tt>
+on a blocking, listening socket may be a recycled socket previously used
+in a <tt>PR_TransmitFile()</tt> call. Since <tt>PR_TransmitFile()</tt>
+only operates in blocking mode, this recycled socket can only be reused
+in blocking mode, hence the above constraint.
+
+Because these constraints only apply to NT, it is advised that you test
+your cross-platform code that uses nonblocking io on NT early in the
+development cycle. These constraints are enforced in the debug NSPR
+library by assertions.
+

+
+Differences from Blocking IO
+----------------------------
+
+- In nonblocking mode, the timeout argument for the io functions is
+ ignored.
+- <tt>PR_AcceptRead()</tt> and <tt>PR_TransmitFile()</tt> only work on
+ blocking sockets. They do not make sense in nonblocking mode.
+- <tt>PR_Write()</tt>, <tt>PR_Send()</tt>, <tt>PR_Writev()</tt> in
+ blocking mode block until the entire buffer is sent. In nonblocking
+ mode, they cannot block, so they may return with just sending part of
+ the buffer.
+
+.. _PR_Poll()_or_PR_Select():
+
+PR_Poll() or PR_Select()?
+-------------------------
+
+<tt>PR_Select()</tt> is deprecated, now declared in
+<tt>private/pprio.h</tt>. Use <tt>PR_Poll()</tt> instead.
+
+The current implementation of <tt>PR_Select()</tt> simply calls
+<tt>PR_Poll()</tt>, so it is sure to have worse performance. Also,
+native file descriptors (socket handles) cannot be added to
+<tt>PR_fd_set</tt>, i.e., the functions <tt>PR_FD_NSET</tt>,
+<tt>PR_FD_NCLR</tt>, <tt>PR_FD_NISSET</tt> do not work.
+
+PR_Available()
+--------------
+
+When <tt>PR_Available()</tt> returns 0, it may mean one of two things:
+
+- There is no data available for reading on that socket. I.e.,
+ <tt>PR_Recv()</tt> would block (a blocking socket) or fail with
+ <tt>PR_WOULD_BLOCK_ERROR</tt> (a nonblocking socket).
+- The TCP connection on that socket has been closed (end of stream).
+
+These two cases can be distinguished by <tt>PR_Poll()</tt>. If
+<tt>PR_Poll()</tt> reports that the socket is readable (i.e.,
+<tt>PR_POLL_READ</tt> is set in <tt>out_flags</tt>), and
+<tt>PR_Available()</tt> returns 0, this means that the socket connection
+is closed.

+Non-blocking layered I/O
+========================
+
+*[last edited by AOF 24 March 1998 14:15]*
+I've recently been working on a long standing issue regarding NSPR's I/O
+model. For a long time I've believed that the non-blocking I/O prevalent
+in classic operating systems (e.g., UNIX) was the major determent for
+having an reasonable layered protocols. Now that I have some first hand
+experience, albeit just a silly little test program, I am more convinced
+that ever of this truth.
+
+This memo is some of what I think must be done in NSPR's I/O subsystem
+to make layered, non-blocking protocols workable. It is just a proposal.
+There is an API change.
+
+Layered I/O
+-----------
+
+NSPR 2.0 defines a structure by which one may define I/O layers. Each
+layer looks basically like any other in that it still uses a
+:ref:`PRFileDesc` as a object identifier, complete with the
+**``IOMethods``** table of functions. However, each layer may override
+default behavior of a particular operation to implement other services.
+For instance, the experiment at hand is one that implements a little
+reliable echo protocol; the client sends *n* bytes, and the same bytes
+get echoed back by the server. In the non-layered design of this it is
+straight forward.
+The goal of the experiment was to put a layer between the client and
+the network, and not have the client know about it. This additional
+layer is one that, before sending the client's data, must ask permission
+from the peer layer to send that many bytes. It imposes an additional
+send and response inside of each client visible send operation. The
+receive operations parallel the sends. Before actually receiving real
+client data, the layer receives a notification that the other would like
+to send some bytes. The layer is responsible for granting permission for
+that data to be sent, then actually receiving the data itself, which is
+delivered to the client.
+
+The synchronous form of the layer's operation is straight forward. A
+call to receive (:ref:`PR_Recv`) first receives the request to send,
+sends (:ref:`PR_Send`) the grant, then receives the actual data
+(:ref:`PR_Recv`). All the client of the layer sees is the data coming
+in. Similar behavior is observed on the sending side.
+
+Non-blocking layered
+--------------------
+
+The non-blocking method is not so simple. Any of the I/O operations
+potentially result in an indication that no progress can be made. The
+intermediate layers cannot act directly on this information, but must
+store the state of the I/O operation until it can be resumed. The method
+for determining that a I/O operation can make progress is to call
+:ref:`PR_Poll` and indicating what type of progress is desired,
+either input or output (or some others). Therein lies the problem.
+The intermediate layer is performing operations that the client is
+unaware. So when the client calls send (:ref:`PR_Send`) and is told
+that the operation would block, it is possible that the layer below is
+actually doing a receive (:ref:`PR_Recv`). The problem is that the
+flag bits passed to :ref:`PR_Poll` are only reflective of the
+client's knowledge and desires. This is further complicated by the fact
+that :ref:`PR_Poll` is not layered. That is each layer does not have
+the opportunity to override the behavior. It operates, not on a single
+file descriptor (:ref:`PRFileDesc`), but on an arbitrary collection of
+file descriptors.
+
+Into the picture comes another I/O method, **``poll()``**. Keep in mind
+that all I/O methods are those that are part of the I/O methods table
+structure (:ref:`PRIOMethods`). These functions are layered, and layers
+may and sometimes must override their behavior by offering unique
+implementations. The **``poll()``** method is used to provide two
+modifying aspects to the semantics of :ref:`PR_Poll`: redefining the
+polling bits (i.e., what to poll for) and to indicate that a layer is
+already able to make progress in the manner suggested by the polling
+bits.
+
+The **``poll()``** method is called by :ref:`PR_Poll` as the latter
+is building the structure to provide the operating system call. The
+stack's top layer will be called first. Each layer's implementation is
+responsible for performing appropriate operations and possibly calling
+the next lower layer's **``poll()``** method.
+What the poll method is returning are the appropriate flags to assign to
+the operating system's call. A layer would compute these based on the
+values of the argument **``in_flags``** and possibly some state
+maintained by the layer for the particular file descriptor.
+
+Additionally, if the layer has buffered data that will allow the
+operation defined by **``in_flags``** to make progress, it will set
+corresponding bits in **``out_flags``**. For instance, if
+**``in_flags``** indicates that the client (or higher layer) wishes to
+test for read ready and the layer has input data buffered, it would set
+the read bits in the **``out_flags``**. If that is the case, then it
+should also suppress the calling of the next lower layer's
+**``poll()``** method and return a value equal to that of
+**``in_flags``**.

+NSPR build instructions
+=======================
+
+Prerequisites
+~~~~~~~~~~~~~
+
+On Windows, the NSPR build system needs GNU make and a Unix command-line
+utility suite such as MKS Toolkit, Cygwin, and MSYS. The easiest way to
+get these tools is to install the
+:ref:`MozillaBuild` package.
+
+Introduction
+~~~~~~~~~~~~
+
+The top level of the NSPR source tree is the ``mozilla/nsprpub``
+directory. Although ``nsprpub`` is a subdirectory under ``mozilla``,
+NSPR is independent of the Mozilla client source tree.
+
+Building NSPR consists of three steps:
+
+#. run the configure script. You may override the compilers (the CC
+ environment variable) or specify options.
+#. build the libraries
+#. build the test programs
+
+For example,
+
+::
+
+ # check out the source tree from Mercurial
+ hg clone https://hg.mozilla.org/projects/nspr
+ # create a build directory
+ mkdir target.debug
+ cd target.debug
+ # run the configure script
+ ../nspr/configure [optional configure options]
+ # build the libraries
+ gmake
+ # build the test programs
+ cd pr/tests
+ gmake
+
+On Mac OS X, use ``make``, which is GNU ``make``.
+
+.. _Configure_options:
+
+Configure options
+~~~~~~~~~~~~~~~~~
+
+Although NSPR uses autoconf, its configure script has two default values
+that are different from most open source projects.
+
+#. If the OS vendor provides a compiler (for example, Sun and HP), NSPR
+ uses that compiler instead of GCC by default.
+#. NSPR build generates a debug build by default.
+
+.. _--disable-debug_--enable-optimize:
+
+--disable-debug --enable-optimize
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Specify these two options to generate an optimized (release) build.
+
+These two options can actually be used independently, but it's not
+recommended.
+
+--enable-64bit
+^^^^^^^^^^^^^^
+
+On a dual 32-bit/64-bit platform, NSPR build generates a 32-bit build by
+default. To generate a 64-bit build, specify the ``--enable-64bit``
+configure option.
+
+.. _--targetx86_64-pc-mingw32:
+
+--target=x86_64-pc-mingw32
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For 64-bit builds on Windows, when using the mozbuild environment.
+
+.. _--enable-win32-target.3DWIN95:
+
+--enable-win32-target=WIN95
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This option is only used on Windows. NSPR build generates a "WINNT"
+configuration by default on Windows for historical reasons. We recommend
+most applications use the "WIN95" configuration. The "WIN95"
+configuration supports all versions of Windows. The "WIN95" name is
+historical; it should have been named "WIN32".
+
+To generate a "WIN95" configuration, specify the
+``--enable-win32-target=WIN95`` configure option.
+
+.. _--enable-debug-rtl:
+
+--enable-debug-rtl
+^^^^^^^^^^^^^^^^^^
+
+This option is only used on Windows. NSPR debug build uses the release C
+run-time library by default. To generate a debug build that uses the
+debug C run-time library, specify the ``--enable-debug-rtl`` configure
+option.
+
+.. _Makefile_targets:
+
+Makefile targets
+~~~~~~~~~~~~~~~~
+
+- all (default)
+- clean
+- realclean
+- distclean
+- install
+- release
+
+.. _Running_the_test_programs:
+
+Running the test programs
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The tests were built above, in the ``pr/tests`` directory.
+
+On Mac OS X, they can be executed with the following:
+
+.. code::
+
+ /bin/sh:
+
+ $ cd pr/tests
+ $ DYLD_LIBRARY_PATH=../../dist/lib ./accept
+ PASS
+ $
+ $ # to run all the NSPR tests...
+ $
+ $ DYLD_LIBRARY_PATH=../../dist/lib ../../../nspr/pr/tests/runtests.sh ../..

+NSPR contributor guide
+======================
+
+**Abstract:**
+
+ NSPR accepts contributions in the form of bugfixes, new features,
+ libraries, platform ports, documentation, test cases and other items
+ from many sources. We (the NSPR module owners) sometimes disappoint
+ our contributors when we must reject their contributions. We reject
+ contributions for a variety of reasons. Some of these reasons are not
+ obvious to an outside observer. NSPR wishes to document some
+ guidelines for those who would contribute to NSPR. These guidelines
+ should help the contributor in crafting his contribution, increasing
+ its likelihood for acceptance.
+
+General Guidelines
+~~~~~~~~~~~~~~~~~~
+
+*Downward Compatibility*
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Because many different applications, besides the mozilla client, use the
+NSPR API, the API must remain downward compatible across even major
+releases. This means that the behavior of an existing public API item in
+NSPR cannot change. Should you need to have a similar API, with some
+slightly different behavior or different function prototype, then
+suggest a new API with a different name.
+
+*C Language API*
+^^^^^^^^^^^^^^^^
+
+The NSPR API is a C Language API. Please do not contribute Java, C or
+other language wrappers.
+
+*Coding Style*
+^^^^^^^^^^^^^^
+
+NSPR does not have a documented coding style guide. Look at the extant
+code. Make yours look like that. Some guidelines concerning naming
+conventions can be found in :ref:`NSPR_Naming_Conventions`.
+in the :ref:`NSPR API Reference`.
+
+*Ownership of your contribution*
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When you contribute something to NSPR, you must have intellectual
+property rights to that contribution. This means that you cannot give us
+something you snatched from somewhere else;. it must be your own
+invention, free and clear of encumberment of anyone or anything else;
+pay close attention to the rights of your "Day-Job" employer. If you
+snatched it from somewhere else, tell us where; show us where the right
+to incorporate it into NSPR exists.
+
+*License under MPL or GPL*
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When you contribute material to NSPR, you agree to allow your
+contribution to be licensed under the MPL or GPL.
+
+BugFixes
+~~~~~~~~
+
+Use `Bugzilla <https://bugzilla.mozilla.org/>`__ to track bugs. Document
+the bug or use an existing report. Be verbose in describing what you are
+doing and why.
+
+Include your changes as diffs in an attachment to the BugZilla report.
+
+Use a coding style consistent with the source file you are changing.
+
+New Features
+~~~~~~~~~~~~
+
+For purposes of this paper, a "new feature" is defined as some API
+addition that goes into the core NSPR library, for example:
+``libnspr4.dll``
+
+NSPR is mostly complete. New APIs are driven mostly by the OS vendors as
+they add new features. Should you decide that there's something that
+NSPR does not cover that should be covered, let's talk. Your proposed
+API should encapsulate a relatively low level capability as would be
+found in a system call or libc.
+
+Your new feature must be implemented on all platforms supported by NSPR.
+When you consider a new API for NSPR ask yourself if your proposed
+feature can implement it across all platforms supported by NSPR. If
+several platforms cannot be made to implement your API, then it is not a
+good candidate for inclusion in NSPR.
+
+Before you begin what may be a substantial effort in making a candidate
+feature for NSPR, talk to us. We may tell you that you have a good idea;
+we may say that it really is not a good candidate for inclusion in NSPR;
+we may give you suggestions on what would make it more generalized,
+hence a good candidate for inclusion in NSPR.
+
+Use `Bugzilla <https://bugzilla.mozilla.org>`__ to track your work. Be
+verbose.
+
+NSPR wants you to document your work. If we accept it, we are going to
+have to answer questions about it and/or maintain it. These are some
+guidelines for new APIs that you may add to NSPR.
+
+**Header File Descriptions**. Provide header file descriptions that
+fully document your public typedefs, enums, macros and functions.
+
+See:
+`prshm.h <http://lxr.mozilla.org/nspr/source/nsprpub/pr/include/prshm.h>`__
+as an example of how your header file(s) should be documented.
+
+*Source File Descriptions*o. Provide descriptive documentation in your
+source (*.c) files. Alas, we have no source files documented as we think
+they should be.
+
+The following are some general guidelines to use when implementing new
+features:
+
+- Don't export global variables
+- Your code must be thread safe
+- You must provide test cases that test all APIs you are adding. See:
+ [#TestCases Test Cases]
+
+New Libraries
+~~~~~~~~~~~~~
+
+All the guidelines applicable to [#NewFeatures New Features] applies to
+new libraries.
+
+For purposes of this paper, a "new library" is defined as a library under
+the ``mozilla/nsprpub/lib`` directory tree and built as a separate
+library. These libraries exist, for the most part, as "legacy" code from
+NSPR 1.0. [Note that the current NSPR module owners do not now nor never
+have been involved with NSPR 1.0.]. Such is life. That said: There are
+some libraries that implement functions intended for use with
+applications using NSPR, such as ``...nsprpub/lib/libc/plgetopt.*.``
+
+- generally useful
+- platform abstractions
+- you agree to sustain, bug fix
+- May rely on the NSPR API
+- May NOT rely on any other library API
+
+New Platform Ports
+~~~~~~~~~~~~~~~~~~
+
+- all NSPR API items must be implemented
+- platform specific headers in ``pr/include/md/_platformname.[h!cfg]``
+- platform specific code in ``pr/src/md/platform/*.c``
+- make rules in ``config/_platform.mk``
+
+Documentation
+~~~~~~~~~~~~~
+
+The files for NSPR's documentation are maintained using a proprietary
+word processing system [don't ask]. Document your work as described in
+[#NewFeatures New Features]. Use the style of other NSPR documentation.
+We will see that your documentation is transcribed into the appropriate
+word processor and the derived HTML shows up on mozilla.org
+
+Test Cases
+~~~~~~~~~~
+
+You should provide test cases for all new features and new libraries.
+
+Give consideration to providing a test case when fixing a bug if an
+existing test case did not catch a bug it should have caught.
+
+The new test cases should be implemented in the style of other NSPR test
+cases.
+
+Test cases should prove that the added API items work as advertised.
+
+Test cases should serve as an example of how to use the API items.
+
+Test cases should provoke failure of every API item and report its
+failure.
+

+NSPR pool method
+================
+
+This technical note documents the poll method of PRFileDesc. The poll
+method is not to be confused with the PR_Poll function. The poll method
+operates on a single NetScape Portable Runtime (NSPR) file descriptor,
+whereas PR_Poll operates on a collection of NSPR file descriptors.
+PR_Poll uses the poll method behind the scene, but it is also possible
+to use the poll method directly.
+
+We consider a stack of *NSPR I/O layers* on top of the *network
+transport*. Each I/O layer is represented by a PRFileDesc structure and
+the protocol of that layer is implemented by a PRIOMethods table. The
+bottom layer is a wrapper for the underlying network transport. The NSPR
+library provides a reference implementation of the bottom layer using
+the sockets API, but you can provide your own implementation of the
+bottom layer using another network transport API. The poll method is one
+of the functions in the PRIOMethods table. The prototype of the poll
+method is
+
+.. code::
+
+ PRInt16 poll_method(PRFileDesc *fd, PRInt16 in_flags, PRInt16 *out_flags);
+
+The purpose of the poll method is to allow a layer to modify that flags
+that will ultimately be used in the call to the underlying network
+transport's select (or equivalent) function, and to indicate that a
+layer is already able to make progress in the manner suggested by the
+polling flags. The arguments and return value of the poll method are
+described below.
+
+.. _in_flags_input_argument:
+
+in_flags [input argument]
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The in_flags argument specifies the events at the **top layer** of the
+I/O layer stack that the caller is interested in.
+
+- For PR_Recv, you should pass PR_POLL_READ as the in_flags argument to
+ the poll method
+- For PR_Send, you should pass PR_POLL_WRITE as the in_flags argument
+ to the poll method
+
+.. _out_flags_output_argument:
+
+out_flags [output argument]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If an I/O layer is ready to satisfy the I/O request defined by in_flags
+without involving the underlying network transport, its poll method sets
+the corresponding event in \*out_flags on return.
+
+For example, consider an I/O layer that buffers input data. If the
+caller wishes to test for read ready (that is, PR_POLL_READ is set in
+in_flags) and the layer has input data buffered, the poll method would
+set the PR_POLL_READ event in \*out_flags. It can determine that without
+asking the underlying network transport.
+
+The current implementation of PR_Poll (the primary user of the poll
+method) requires that the events in \*out_flags reflect the caller's
+view. This requirement may be relaxed in a future NSPR release. To
+remain compatible with this potential semantic change, NSPR clients
+should only use \*out_flags as described in the *How to use the poll
+method* section below.
+
+.. _Return_value:
+
+Return value
+~~~~~~~~~~~~
+
+If the poll method stores a nonzero value in \*out_flags, the return
+value will be the value of in_flags. (Note: this may change in a future
+NSPR release if we make the semantic change to \*out_flags mentioned
+above. Therefore, NSPR clients should only use the return value as
+described in *How to use the poll method* section below.) If the poll
+method stores zero in \*out_flags, the return value will be the bottom
+layer's desires with respect to the in_flags. Those are the events that
+the caller should poll the underlying network transport for. These
+events may be different from the events in in_flags (which reflect the
+caller's view) for some protocols.
+
+.. _How_to_use_the_poll_method:
+
+How to use the poll method
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The poll method should only be used with a NSPR file descriptor in
+**non-blocking** mode. Most NSPR clients call PR_Poll and do not call
+the poll method directly. However, PR_Poll can only used with a stack
+whose bottom layer is NSPR's reference implementation. If you are using
+your own implementation of the bottom layer, you must call the poll
+method as follows.
+
+Declare two PRInt16 variables to receive the return value and the
+out_flags output argument of the poll method.
+
+.. code::
+
+ PRInt16 new_flags, out_flags;
+
+If you are going to call PR_Recv, pass PR_POLL_READ as the in_flags
+argument.
+
+.. code::
+
+ new_flags = fd->methods->poll(fd, PR_POLL_READ, &out_flags);
+
+If you are going to call PR_Send, pass PR_POLL_WRITE as the in_flags
+argument.
+
+.. code::
+
+ new_flags = fd->methods->poll(fd, PR_POLL_WRITE, &out_flags);
+
+If you are interested in calling both PR_Recv and PR_Send on the same
+file descriptor, make two separate calls to the poll method, one with
+PR_POLL_READ as in_flags and the other with PR_POLL_WRITE as in_flags,
+so that you know what events at the network transport layer PR_POLL_READ
+and PR_POLL_WRITE are mapped to, respectively.
+
+On return, if (new_flags & out_flags) is nonzero, you can try PR_Recv or
+PR_Send immediately.
+
+Otherwise ((new_flags & out_flags) is 0), you should do the following.
+
+- If new_flags contains PR_POLL_READ, you should try PR_Recv or PR_Send
+ when the underlying network transport is readable
+- If new_flags contains PR_POLL_WRITE, you should try PR_Recv or
+ PR_Send when the underlying network transport is writable
+
+**Important** do not use out_flags in any way other than testing if
+(new_flags & out_flags) is 0. This is how PR_Poll (the primary user and
+hence the de facto specification of the poll method) uses out_flags.

+
+Binary distributions
+~~~~~~~~~~~~~~~~~~~~
+
+Right now I use the ``mozilla/nsprpub/admin/repackage.sh`` script to
+generate the binary distributions published on ftp.mozilla.org. As the
+name of the shell script implies, ``repackage.sh`` merely repackages
+binary distributions in a different format.
+
+Before you run ``repackage.sh``, you need to have built the binary
+distributions using the "gmake release" makefile target. These binary
+distributions are jar files, which are really zip files, and they are
+published in the directory ``/share/builds/components``. This design
+comes from the Netscape days.
+
+The ``repackage.sh`` script repackages the jar files into the form most
+commonly used on that platform. So on Unix it repackages the jar files
+into gzipped tar files, and on Windows it repackages the jar files into
+zip files.
+
+Edit the ``repackage.sh`` script to customize it for your environment.
+
+After you have run ``repackage.sh``, follow the
+`instructions <http://www.mozilla.org/build/ftp-stage.html>`__ in to
+upload the files to ftp.mozilla.org's staging server, so that they
+eventually show up on ftp.mozilla.org. The host ftp.mozilla.org can be
+accessed via the ftp, http, and https protocols. We recommend using
+https://ftp.mozilla.org/.
+
+**Note:** For NSS, the script equivalent to NSPR's ``repackage.sh`` is
+``/u/robobld/bin/sbsinit/nss/push/buildbindist.sh`` in the "SVBuild"
+source tree.

+NSPR's position on abrupt thread termination
+============================================
+
+This memo describes my position on a facility that is currently under
+discussion for inclusion in the NetScape Portable Runtime (NSPR); the
+ability of a thread to abruptly exit. I resist including this function
+in NSPR because it results in bad programming practice and unsupportable
+programs.
+
+ *Threads are not processes.*
+
+Abrupt termination has been available in the UNIX/C environment for some
+time (``exit()``), and I assume that the basic semantics defined there
+are applicable here. In that environment, ``exit()`` may be called and
+any time, and results in the calling thread's immediate termination. In
+the situation where it was defined (UNIX), which has only a single
+thread of execution, that is equivalent to terminating the process. The
+process abstraction is then responsible for closing all open files and
+reclaiming all storage that may have been allocated during the process'
+lifetime.
+
+This practice does not extend to threads. Threads run within the
+confines of a process (or similar abstractions in other environments).
+Threads are lightweight because they do not maintain the full protection
+domain provided by a process. So in a threaded environment, what is the
+parallel to UNIX' ``exit()``?
+
+NSPR has defined a function, callable by any thread within a process at
+any time, called ``PR_ProcessExit()``. This is identical to UNIX
+``exit()`` and was so named in an effort to make the obvious even more
+so. When called, the process exits, closing files and reclaiming the
+process' storage.
+
+Certain people have been disappointed when NSPR did not provide a
+functional equivalent to exit just a particular thread. Apparently they
+have failed to consider the ramifications. If a thread was to abruptly
+terminate, there is no recording of what resources it owns and should
+therefore be reclaimed. Those resources are in fact, owned by the
+process and shared by all the threads within the process.
+
+In the general course of events when programming with threads, it is
+very advantageous for a thread to have resources that it and only it
+knows about. In the natural course of events, these resources will be
+allocated by a thread, used for some period of time, and then freed as
+the stack unwinds. In these cases, the presence of the data is recorded
+only on the stack, known only to the single thread (normally referred to
+as *encapsulated*).
+
+The problem with abrupt termination is that it can happen at any time,
+to a thread that is coded correctly to handle both normal and
+exceptional situations, but will be unable to do so since it will be
+denied the opportunity to complete execution. It can happen because it
+called out of its own scope into some lazily implemented library.
+
+NSPR's answer to this is that there is no abrupt thread termination. All
+threads must unwind and return from their root function. If they cannot,
+because of some state corruption, then they must assume that the
+corruption, like the state, is shared, and their only resource is for
+the process to terminate.
+
+To make this solution work requires that a function that encounters an
+error be designed such that it first repairs its immediate state, and
+then reports that error to its caller. If the caller cannot deal with
+the failure, it must do the same. This process continues until the
+thread either recovers from the malady or returns from the root
+function. This is not all that difficult (though having done it a number
+of times to already existing code, I will admit it isn't much fun
+either).
+
+The implementation of either strategy within the NSPR runtime is not
+difficult. That is not what this memo is about. This is about providing
+an API that coaxes people to do the right thing in as many ways as
+possible. The existence of ``exit()`` in the UNIX/C environment is a
+perfect example of how programmers will employ the most expediant
+solution available. The definition of the language C is such that
+returning from ``main()`` is a perfectly fine thing to do. But what
+percentage of C programs actually bother? In UNIX, with its complex
+definition of a protection domain, it happens to work (one might even
+say it's more efficient) to exit from anywhere. But threads are not
+processes. If threads have to maintain the same type of resource
+knowledge as a process, they loose all of their benefit.
+
+Threads are an implementation strategy to provide the illusion of
+concurrency within a process. They are alternatives to large state
+machines with mostly non-blocking library functions. When the latter is
+used to provide concurrency, calling ``exit()`` will terminate the
+entire process. Why would anyone expect a thread to behave differently?
+Threads are not processes.

+Optimizing applications for NSPR
+================================
+
+NetScape Portable Runtime (NSPR) tries to provide a consistent level of
+service across the platforms it supports. This has proven to be quite
+challenging, a challenge that was met to a large degree, but there is
+always room for improvement. The casual client may not encounter a need
+to know the details of the shortcomings to the level described here, but
+if and when clients become more sophisticated, these issues will
+certainly surface.
+
+ *This memo is by no way complete.*
+
+Multiplatform
+-------------
+
+- Do not call any blocking system call from a local thread. The only
+ exception to this rule is the <tt>select()</tt> and <tt>poll()</tt>
+ system calls on Unix, both of which NSPR has overridden to make sure
+ they are aware of the NSPR local threads.
+- In the combined (MxN) model, which includes NT, IRIX (sprocs), and
+ pthreads-user, the primordial thread is always a local thread.
+ Therefore, if you call a blocking system call from the primordial
+ thread, it is going to block more than just the primordial thread and
+ the system may not function correctly. On NT, this problem is
+ especially obvious because the idle thread, which is in charge of
+ driving the asynch io completion port, is also blocked. Do not call
+ blocking system calls from the primordial thread. Create a global
+ thread and call the system call in that thread, and have the
+ primordial thread join that thread.
+- NSPR uses timer signals to implement thread preemption for local
+ threads on some platforms. If all the software linked into the
+ application is not ported to the NSPR API, the application may fail
+ because of threads being preempted during critical sections. To
+ disable thread preemption call
+ <tt>PR_DisableClockInterrupts()</tt>during initialization.
+- Interrupting threads (via <tt>PR_Interrupt()</tt>) on threads blocked
+ in I/O functions is implemented to various degrees on different
+ platforms. The UNIX based platforms all implement the function though
+ there may be up to a 5 second delay in processing the request.
+- The mechanism used to implement <tt>PR_Interrupt()</tt> on the
+ *pthreads* versions of NSPR is flawed. No failure attributable to the
+ flaw has shown up in any tests or products - yet. The specific area
+ surrounding pthread's *continuation thread* has been both observed
+ and empirically proven faulty, and a correction identified.

+NSPR platforms
+==============
+
+Build System and Supported Platforms
+------------------------------------
+
+NSPR has been implemented on over 20 platforms. A platform may have
+more than one implementation strategy of its multi threading and I/O
+facilities. This article explains the NSPR build system and how to
+specify a particular implementation strategy, compiler or compiler
+switches, or the target OS for your build on each platform.
+
+Implementation Strategies
+-------------------------
+
+Threads are at the core of NSPR, and the I/O functions are tied to the
+multi threading facilities because many I/O functions may block the
+calling threads. NSPR has multiple implementation strategies of its
+multi threading and I/O functions. The various implementation strategies
+can be organized into the hierarchy below:
+
+- **Classic NSPR** (This is our first code base, hence the term
+ "classic NSPR"):
+
+**Local threads only**: All threads are user-level threads implemented
+by NSPR.
+**Global threads only**: All threads are native threads supplied by the
+OS vendor. For example, Solaris UI (Unix International) threads and
+Win32 threads.
+**Combined**: NSPR multiplexes user-level threads on top of native,
+kernel-level threads. This is also called the MxN model. At present,
+there are three implementations of the combined model.
+
+- IRIX: sprocs + NSPR user-level threads
+- Windows NT: Win32 threads + NT fibers
+- **Pthreads-user**: kernel-level pthreads + NSPR user-level threads
+
+**Pthreads**: All threads are pthreads. The relevant code is in
+``mozilla/nsprpub/pr/src/pthreads`` (threads and I/O).
+Classic NSPR and pthreads have relatively disjoint code bases in the
+threads and I/O areas:
+
+- Classic NSPR: ``mozilla/nsprpub/pr/src/threads/combined`` (threads),
+ ``mozilla/nsprpub/pr/src/io`` (I/O)
+- Pthreads: ``mozilla/nsprpub/pr/src/pthreads`` (threads and I/O)
+
+Note that some files under ``mozilla/nsprpub/pr/src/io`` are shared by
+both classic NSPR and pthreads. Consult
+``mozilla/nsprpub/pr/src/Makefile`` for the definitive list of files
+used by each implementation strategy (see the definition of the makefile
+variable ``OBJS``).
+
+Compilers
+---------
+
+For ease of integration with third-party libraries, which may use native
+threads, NSPR uses the native threads whenever possible. As a result,
+native compilers are used to build NSPR on most platforms because they
+have better debugging support for native threads. The only exception is
+Solaris, where both cc and gcc are used.
+
+NSPR Build System
+-----------------
+
+NSPR build system is based on GNU make.
+We use GNU make 3.74 on Unix, but our makefiles should
+work fine under newer versions of GNU make.
+
+Every directory in NSPR has a makefile named ``Makefile``, which
+includes the makefile fragments in ``mozilla/nsprpub/config``. NSPR
+makefiles implement the common Makefile targets such as
+``export``, ``libs``, and ``install``. However, some makefiles targets
+are no-op in NSPR because they are not necessary for NSPR.
+
+To build NSPR, change directory to the root of our source tree
+``cd mozilla/nsprpub``
+and then issue the command
+``gmake``
+Make will recursively go into all the subdirectories and the right
+things will happen.
+
+The table below lists the common NSPR makefile targets.
+
++-----------------------------------+-----------------------------------+
+| ``all`` | The default target. Same as |
+| | ``export`` ``libs`` ``install``. |
++-----------------------------------+-----------------------------------+

+| ``depend`` | No-op. **This means that NSPR |
+| | makefiles do not have header file |
+| | dependencies.** |
++-----------------------------------+-----------------------------------+
+| ``clean`` | Remove ``.o`` files. |
++-----------------------------------+-----------------------------------+
+| ``clobber`` | Remove ``.o`` files, libraries, |
+| | and executable programs. |
++-----------------------------------+-----------------------------------+
+| ``realclean`` | Remove all generated files and |

+Process forking in NSPR
+=======================
+
+The threads provided in NetScape Portable Runtime (NSPR) are implemented
+using different mechanisms on the various platforms. On some platforms,
+NSPR threads directly map one-to-one to the threads provided by the
+platform vendor, on other platforms NSPR threads are basically
+user-level threads within a single process (with no kernel threads) and
+on still others NSPR threads are user-level threads implemented on top
+of one or more kernel threads within single address space.
+
+NSPR does not override the fork function and so, when fork is called
+from the NSPR thread the results are different on the various platforms.
+All the threads present in the parent process may be replicated in the
+child process, only the calling thread may be replicated in the child
+process or only the calling kernel thread may be replicated.
+
+So, to be consistent across all platforms, it is suggested that when
+using fork in a NSPR thread;
+
+#. The exec function should be called in the child process.
+#. No NSPR functions should be called in the child process before the
+ exec call is made.

+Anonymous Shared Memory
+=======================
+
+This chapter describes the NSPR API for anonymous shared memory.

+
+.. _Anonymous_Memory_Protocol:
+
+Anonymous Memory Protocol
+-------------------------
+
+NSPR provides an anonymous shared memory based on NSPR's :ref:`PRFileMap`
+type. The anonymous file-mapped shared memory provides an inheritable
+shared memory, as in: the child process inherits the shared memory.
+Compare the file-mapped anonymous shared memory to to a named shared
+memory described in prshm.h. The intent is to provide a shared memory
+that is accessible only by parent and child processes. ... It's a
+security thing.
+
+Depending on the underlying platform, the file-mapped shared memory may
+be backed by a file. ... surprise! ... On some platforms, no real file
+backs the shared memory. On platforms where the shared memory is backed
+by a file, the file's name in the filesystem is visible to other
+processes for only the duration of the creation of the file, hopefully a
+very short time. This restricts processes that do not inherit the shared
+memory from opening the file and reading or writing its contents.
+Further, when all processes using an anonymous shared memory terminate,
+the backing file is deleted. ... If you are not paranoid, you're not
+paying attention.
+
+The file-mapped shared memory requires a protocol for the parent process
+and child process to share the memory. NSPR provides two protocols. Use
+one or the other; don't mix and match.
+
+In the first protocol, the job of passing the inheritable shared memory
+is done via helper-functions with PR_CreateProcess. In the second
+protocol, the parent process is responsible for creating the child
+process; the parent and child are mutually responsible for passing a
+``FileMap`` string. NSPR provides helper functions for extracting data
+from the :ref:`PRFileMap` object. ... See the examples below.
+
+Both sides should adhere strictly to the protocol for proper operation.
+The pseudo-code below shows the use of a file-mapped shared memory by a
+parent and child processes. In the examples, the server creates the
+file-mapped shared memory, the client attaches to it.

+This chapter describes the date and time functions in NSPR.
+
+NSPR represents time in two ways, absolute time and clock/calendar time.
+NSPR provides types and constants for both representations, and
+functions to convert time values between the two.
+
+- Absolute time representation treats time instants as points along the
+ time line. A time instant is represented by its position on the time
+ line relative to the origin, called the epoch. NSPR defines the epoch
+ to be midnight (00:00:00) 1 January 1970 UTC (Coordinated Universal
+ Time). In this form, time is just a point on the time line. There is
+ no notion of time zone.
+
+- Clock/calendar time, used for human interfaces, represents time in
+ the familiar year, month, day, hour, minute, second components. In
+ this form, the time zone information is important. For example,
+ without specifying the time zone, the time 8:00AM 1 May 1998 is
+ ambiguous. The NSPR data type for clock/calendar time, called an
+ exploded time, has the time zone information in it, so that its
+ corresponding point in absolute time is uniquely specified.
+
+Note that absolute and clock times are not normally used in timing
+operations. For functions that deal with the measurement of elapsed time
+and with timeouts, see `Interval Timing <Interval_Timing>`__.

+Dynamic Library Search
+======================
+
+This section describes NSPR's programming interface to load, unload and
+resolve symbols in dynamic libraries. It also provides a method by which
+to condition symbols of statically linked code so that to other clients
+it appears as though they are dynamically loaded.
+
+.. _Library_Linking_Types:
+
+Library Linking Types
+---------------------
+
+These data types are defined for dynamic library linking:
+
+ - :ref:`PRLibrary`
+ - :ref:`PRStaticLinkTable`
+
+.. _Library_Linking_Functions:
+
+Library Linking Functions
+-------------------------
+
+The library linking functions are:
+
+ - :ref:`PR_SetLibraryPath`
+ - :ref:`PR_GetLibraryPath`
+ - :ref:`PR_GetLibraryName`
+ - :ref:`PR_FreeLibraryName`
+ - :ref:`PR_LoadLibrary`
+ - :ref:`PR_UnloadLibrary`
+ - :ref:`PR_FindSymbol`
+ - :ref:`PR_FindSymbolAndLibrary`
+
+.. _Finding_Symbols_Defined_in_the_Main_Executable_Program:
+
+Finding Symbols Defined in the Main Executable Program
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+:ref:`PR_LoadLibrary` cannot open a handle that references the main
+executable program. (This is admittedly an omission that should be
+fixed.) However, it is possible to look up symbols defined in the main
+executable program as follows.
+
+.. code::
+
+ PRLibrary *lib;
+ void *funcPtr;
+
+ funcPtr = PR_FindSymbolAndLibrary("FunctionName", &lib);
+
+When :ref:`PR_FindSymbolAndLibrary` returns, ``funcPtr`` is the value of
+the function pointer you want to look up, and the variable lib
+references the main executable program. You can then call
+:ref:`PR_FindSymbol` on lib to look up other symbols defined in the main
+program. Remember to call ``PR_UnloadLibrary(lib)`` to close the library
+handle when you are done.
+
+.. _Platform_Notes:
+
+Platform Notes
+--------------
+
+To use the dynamic library loading functions on some platforms, certain
+environment variables must be set at run time, and you may need to link
+your executable programs using special linker options.
+
+This section summarizes these platform idiosyncrasies. For more
+information, consult the man pages for ``ld`` and ``dlopen`` (or
+``shl_load`` on HP-UX) for Unix, and the ``LoadLibrary`` documentation
+for Win32.
+
+- `Dynamic Library Search Path <#Dynamic_Library_Search_Path>`__
+- `Exporting Symbols from the Main Executable
+ Program <#Exporting_Symbols_from_the_Main_Executable_Program>`__
+
+Dynamic Library Search Path
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The dynamic library search path is the list of directories in which to
+look for a dynamic library. Each platform has its own standard
+directories in which to look for dynamic libraries, plus a customizable
+list of directories specified by an environment variable.
+
+- On most Unix systems, this environment variable is
+ ``LD_LIBRARY_PATH``. These systems typically use ``dlopen`` to load a
+ dynamic library.
+- HP-UX uses ``shl_load`` to load dynamic libraries, and the
+ environment variable specifying the dynamic library search path is
+ ``SHLIB_PATH``. Moreover, the executable program must be linked with
+ the +s option so that it will search for shared libraries in the
+ directories specified by ``SHLIB_PATH`` at run time. Alternatively,
+ you can enable the +s option as a postprocessing step using the
+ ``chatr`` tool. For example, link your executable program a.out
+ without the +s option, then execute the following:
+
+.. code::
+
+ chatr +s enable a.out
+
+- On Rhapsody, the environment variable is ``DYLD_LIBRARY_PATH``.
+- On Win32, the environment variable is ``PATH``. The same search path
+ is used to search for executable programs and DLLs.
+
+.. _Exporting_Symbols_from_the_Main_Executable_Program:
+
+Exporting Symbols from the Main Executable Program
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On some systems, symbols defined in the main executable program are not
+exported by default. On HP-UX, you must link the executable program with
+the -E linker option in order to export all symbols in the main program
+to shared libraries. If you use the GNU compilers (on any platform), you
+must also link the executable program with the -E option.

+Functions that Operate on Pathnames
+-----------------------------------
+
+A file or directory in a file system is specified by its pathname. NSPR
+uses Unix-style pathnames, which are null-terminated character strings.
+Only the ASCII character set is supported. The forward slash (/)
+separates the directories in a pathname. NSPR converts the slashes in a
+pathname to the directory separator of the native OS--for example,
+backslash (\) on Windows and colon (:) on Mac OS--before passing it to
+the native system calls.
+
+Some file systems also differentiate drives or volumes.

+Memory-mapped I/O functions are currently implemented for Unix, Linux,

+Polling Functions
+-----------------
+
+This section describes two of the most important polling functions
+provided by NSPR:
+
+- :ref:`PR_Poll`
+- :ref:`PR_GetConnectStatus`
+
+.. _Pollable_Events:
+
+Pollable Events
+---------------
+
+A pollable event is a special kind of file descriptor. The only I/O
+operation you can perform on a pollable event is to poll it with the
+:ref:`PR_POLL_READ` flag. You cannot read from or write to a pollable
+event.
+
+The purpose of a pollable event is to combine event waiting with I/O
+waiting in a single :ref:`PR_Poll` call. Pollable events are implemented
+using a pipe or a pair of TCP sockets connected via the loopback
+address, therefore setting and/or waiting for pollable events are
+expensive operating system calls. Do not use pollable events for general
+thread synchronization; use condition variables instead.
+
+A pollable event has two states: set and unset. Events are not queued,
+so there is no notion of an event count. A pollable event is either set
+or unset.
+
+- :ref:`PR_NewPollableEvent`
+- :ref:`PR_DestroyPollableEvent`
+- :ref:`PR_SetPollableEvent`
+- :ref:`PR_WaitForPollableEvent`
+
+One can call :ref:`PR_Poll` with the :ref:`PR_POLL_READ` flag on a pollable
+event. When the pollable event is set, :ref:`PR_Poll` returns the the
+:ref:`PR_POLL_READ` flag set in the out_flags.
+
+.. _Manipulating_Layers:
+
+Manipulating Layers
+-------------------
+
+File descriptors may be layered. For example, SSL is a layer on top of a
+reliable bytestream layer such as TCP.
+
+Each type of layer has a unique identity, which is allocated by the
+runtime. The layer implementor should associate the identity with all
+layers of that type. It is then possible to scan the chain of layers and
+find a layer that one recognizes and therefore predict that it will
+implement a desired protocol.
+
+A layer can be pushed onto or popped from an existing stack of layers.
+The file descriptor of the top layer can be passed to NSPR I/O
+functions, which invoke the appropriate version of the I/O methods
+polymorphically.
+
+NSPR defines three identities:
+
+.. code::
+
+ #define PR_INVALID_IO_LAYER (PRDescIdentity)-1
+ #define PR_TOP_IO_LAYER (PRDescIdentity)-2
+ #define PR_NSPR_IO_LAYER (PRDescIdentity)0
+
+- :ref:`PR_INVALID_IO_LAYER`: An invalid layer identify (for error
+ return).
+- :ref:`PR_TOP_IO_LAYER`: The identity of the top of the stack.
+- :ref:`PR_NSPR_IO_LAYER`: The identity for the layer implemented by NSPR.
+
+:ref:`PR_TOP_IO_LAYER` may be used as a shorthand for identifying the
+topmost layer of an existing stack. For example, the following lines of
+code are equivalent:
+
+| ``rv = PR_PushIOLayer(stack, PR_TOP_IO_LAYER, my_layer);``
+| ``rv = PR_PushIOLayer(stack, PR_GetLayersIdentity(stack), my_layer);``
+

+File Descriptor Types
+---------------------
+
+NSPR represents I/O objects, such as open files and sockets, by file
+descriptors of type :ref:`PRFileDesc`. This section introduces
+:ref:`PRFileDesc` and related types.
+
+ - :ref:`PRFileDesc`
+ - :ref:`PRIOMethods`
+ - :ref:`PRFilePrivate`
+ - :ref:`PRDescIdentity`
+
+Note that the NSPR documentation follows the Unix convention of using
+the term\ *files* to refer to many kinds of I/O objects. To refer
+specifically to the files in a file system (that is, disk files), this
+documentation uses the term\ *normal files*.
+
+:ref:`PRFileDesc` has an object-oriented flavor. An I/O function on a
+:ref:`PRFileDesc` structure is carried out by invoking the corresponding
+"method" in the I/O methods table (a structure of type :ref:`PRIOMethods`)
+of the :ref:`PRFileDesc` structure (the "object"). Different kinds of I/O
+objects (such as files and sockets) have different I/O methods tables,
+thus implementing different behavior in response to the same I/O
+function call.
+
+NSPR supports the implementation of layered I/O. Each layer is
+represented by a :ref:`PRFileDesc` structure, and the :ref:`PRFileDesc`
+structures for the layers are chained together. Each :ref:`PRFileDesc`
+structure has a field (of type :ref:`PRDescIdentity`) to identify itself in
+the layers. For example, the Netscape implementation of the Secure
+Sockets Layer (SSL) protocol is implemented as an I/O layer on top of
+NSPR's socket layer.

+Interval Time Type and Constants
+--------------------------------
+
+All timed functions in NSPR require a parameter that depicts the amount
+of time allowed to elapse before the operation is declared failed. The
+type of such arguments is :ref:`PRIntervalTime`. Such parameters are common
+in NSPR functions such as those used for I/O operations and operations
+on condition variables.
+
+NSPR 2.0 provides interval times that are efficient in terms of
+performance and storage requirements. Conceptually, they are based on
+free-running counters that increment at a fixed rate without possibility
+of outside influence (as might be observed if one was using a
+time-of-day clock that gets reset due to some administrative action).
+The counters have no fixed epoch and have a finite period. To make use
+of these counters, the application must declare a point in time, the
+epoch, and an amount of time elapsed since that **epoch**, the
+**interval**. In almost all cases the epoch is defined as the value of
+the interval timer at the time it was sampled.

+Introduction to NSPR
+====================
+
+The Netscape Portable Runtime (NSPR) API allows compliant applications
+to use system facilities such as threads, thread synchronization, I/O,
+interval timing, atomic operations, and several other low-level services
+in a platform-independent manner. This chapter introduces key NSPR
+programming concepts and illustrates them with sample code.
+
+NSPR does not provide a platform for porting existing code. It must be
+used from the beginning of a software project.
+
+.. _NSPR_Naming_Conventions:
+
+NSPR Naming Conventions
+-----------------------
+
+Naming of NSPR types, functions, and macros follows the following
+conventions:
+
+- Types exported by NSPR begin with ``PR`` and are followed by
+ intercap-style declarations, like this: :ref:`PRInt`, :ref:`PRFileDesc`
+- Function definitions begin with ``PR_`` and are followed by
+ intercap-style declarations, like this: :ref:`PR_Read``,
+ :ref:`PR_JoinThread``
+- Preprocessor macros begin with the letters ``PR`` and are followed by
+ all uppercase characters separated with the underscore character
+ (``_``), like this: :ref:`PR_BYTES_PER_SHORT`, :ref:`PR_EXTERN`
+
+.. _NSPR_Threads:
+
+NSPR Threads
+------------
+
+NSPR provides an execution environment that promotes the use of
+lightweight threads. Each thread is an execution entity that is
+scheduled independently from other threads in the same process. A thread
+has a limited number of resources that it truly owns. These resources
+include the thread stack and the CPU register set (including PC).
+
+To an NSPR client, a thread is represented by a pointer to an opaque
+structure of type :ref:`PRThread``. A thread is created by an explicit
+client request and remains a valid, independent execution entity until
+it returns from its root function or the process abnormally terminates.
+(:ref:`PRThread` and functions for creating and manipulating threads are
+described in detail in `Threads <Threads>`__.)
+
+NSPR threads are lightweight in the sense that they are cheaper than
+full-blown processes, but they are not free. They achieve the cost
+reduction by relying on their containing process to manage most of the
+resources that they access. This, and the fact that threads share an
+address space with other threads in the same process, makes it important
+to remember that *threads are not processes* .
+
+NSPR threads are scheduled in two separate domains:
+
+- **Local threads** are scheduled within a process only and are handled
+ entirely by NSPR, either by completely emulating threads on each host
+ operating system (OS) that doesn't support threads, or by using the
+ threading facilities of each host OS that does support threads to
+ emulate a relatively large number of local threads by using a
+ relatively small number of native threads.
+
+- **Global threads** are scheduled by the host OS--not by NSPR--either
+ within a process or across processes on the entire host. Global
+ threads correspond to native threads on the host OS.
+
+NSPR threads can also be either user threads or system threads. NSPR
+provides a function, :ref:`PR_Cleanup`, that synchronizes process
+termination. :ref:`PR_Cleanup` waits for the last user thread to exit
+before returning, whereas it ignores system threads when determining
+when a process should exit. This arrangement implies that a system
+thread should not have volatile data that needs to be safely stored
+away.
+
+Priorities for NSPR threads are based loosely on hints provided by the
+client and sometimes constrained by the underlying operating system.
+Therefore, priorities are not rigidly defined. For more information, see
+`Thread Scheduling <#Thread_Scheduling>`__.
+
+In general, it's preferable to create local user threads with normal
+priority and let NSPR take care of the details as appropriate for each
+host OS. It's usually not necessary to create a global thread explicitly
+unless you are planning to port your code only to platforms that provide
+threading services with which you are familiar or unless the thread will
+be executing code that might directly call blocking OS functions.
+
+Threads can also have "per-thread-data" attached to them. Each thread
+has a built-in per-thread error number and error string that are updated
+when NSPR operations fail. It's also possible for NSPR clients to define
+their own per-thread-data. For details, see `Controlling Per-Thread
+Private Data <Threads#Controlling_Per-Thread_Private_Data>`__.
+
+.. _Thread_Scheduling:
+
+Thread Scheduling
+~~~~~~~~~~~~~~~~~
+
+NSPR threads are scheduled by priority and can be preempted or
+interrupted. The sections that follow briefly introduce the NSPR
+approach to these three aspects of thread scheduling.
+
+- `Setting Thread Priorities <#Setting_Thread_Priorities>`__
+- `Preempting Threads <#Preempting_Threads>`__
+- `Interrupting Threads <#Interrupting_Threads>`__
+
+For reference information on the NSPR API used for thread scheduling,
+see `Threads <Threads>`__.
+
+.. _Setting_Thread_Priorities:
+
+Setting Thread Priorities
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The host operating systems supported by NSPR differ widely in the
+mechanisms they use to support thread priorities. In general, an NSPR
+thread of higher priority has a statistically better chance of running
+relative to threads of lower priority. However, because of the multiple
+strategies to provide execution vehicles for threads on various host
+platforms, priorities are not a clearly defined abstraction in NSPR. At
+best they are intended to specify a preference with respect to the
+amount of CPU time that a higher-priority thread might expect relative
+to a lower-priority thread. This preference is still subject to resource
+availability, and must not be used in place of proper synchronization.
+For more information on thread synchronization, see `NSPR Thread
+Synchronization <#NSPR_Thread_Synchronization>`__.
+
+The issue is further muddied by inconsistent offerings from OS vendors
+regarding the priority of their kernel-supported threads. NSPR assumes
+that the priorities of global threads are not manageable, but that the
+host OS will perform some sort of fair scheduling. It's usually
+preferable to create local user threads with normal priority and let
+NSPR and the host take care of the details.
+
+In some NSPR configurations, there may be an arbitrary (and perhaps
+large) number of local threads being supported by a more limited number
+of **virtual processors** (an internal application of global threads).
+In such situations, each virtual processor will have some number of
+local threads associated with it, though exactly which local threads and
+how many may vary over time. NSPR guarantees that for each virtual
+processor the highest-priority, schedulable local thread is the one
+executing. This thread implementation strategy is referred to as the **M
+x N model.**
+
+.. _Preempting_Threads:
+
+Preempting Threads
+^^^^^^^^^^^^^^^^^^
+
+Preemption is the act of taking control away from a ready thread at an
+arbitrary point and giving control to another appropriate thread. It
+might be viewed as taking the executing thread and adding it to the end
+of the ready queue for its appropriate priority, then simply running the
+scheduling algorithm to find the most appropriate thread. The chosen
+thread may be of higher priority, of the same priority, or even the same
+thread. It will not be a thread of lower priority.
+
+Some operating systems cannot be made preemptible (for example, Mac OS
+and Win 16). This puts them at some risk in supporting arbitrary code,
+even if the code is interpreted (Java). Other systems are not
+thread-aware, and their runtime libraries not thread-safe (most versions
+of Unix). These systems can support local level thread abstractions that
+can be made preemptible, but run the risk of library corruption
+(``libc``). Still other operating systems have a native notion of
+threads, and their libraries are thread-aware and support locking.
+However, if local threads are also present, and they are preemptible,
+they are subject to deadlock. At this time, the only safe solutions are
+to turn off preemption (a runtime decision) or to preempt global threads
+only.
+
+.. _Interrupting_Threads:
+
+Interrupting Threads
+^^^^^^^^^^^^^^^^^^^^
+
+NSPR threads are interruptible, with some constraints and
+inconsistencies.
+
+To interrupt a thread, the caller of :ref:`PR_Interrupt` must have the NSPR
+reference to the target thread (:ref:`PRThread`). When the target is
+interrupted, it is rescheduled from the point at which it was blocked,
+with a status error indicating that it was interrupted. NSPR recognizes
+only two areas where a thread may be interrupted: waiting on a condition
+variable and waiting on I/O. In the latter case, interruption does
+cancel the I/O operation. In neither case does being interrupted imply
+the demise of the thread.
+
+.. _NSPR_Thread_Synchronization:
+
+NSPR Thread Synchronization
+---------------------------
+
+Thread synchronization has two aspects: locking and notification.
+Locking prevents access to some resource, such as a piece of shared
+data: that is, it enforces mutual exclusion. Notification involves
+passing synchronization information among cooperating threads.
+
+In NSPR, a **mutual exclusion lock** (or **mutex**) of type :ref:`PRLock`
+controls locking, and associated **condition variables** of type
+:ref:`PRCondVar` communicate changes in state among threads. When a
+programmer associates a mutex with an arbitrary collection of data, the
+mutex provides a protective **monitor** around the data.
+
+.. _Locks_and_Monitors:
+
+Locks and Monitors
+~~~~~~~~~~~~~~~~~~
+
+In general, a monitor is a conceptual entity composed of a mutex, one or
+more condition variables, and the monitored data. Monitors in this
+generic sense should not be confused with the monitor type used in Java
+programming. In addition to :ref:`PRLock`, NSPR provides another mutex
+type, :ref:`PRMonitor`, which is reentrant and can have only one associated
+condition variable. :ref:`PRMonitor` is intended for use with Java and
+reflects the Java approach to thread synchronization.
+
+To access the data in the monitor, the thread performing the access must
+hold the mutex, also described as being "in the monitor." Mutual
+exclusion guarantees that only one thread can be in the monitor at a
+time and that no thread may observe or modify the monitored data without
+being in the monitor.
+
+Monitoring is about protecting data, not code. A **monitored invariant**
+is a Boolean expression over the monitored data. The expression may be
+false only when a thread is in the monitor (holding the monitor's
+mutex). This requirement implies that when a thread first enters the
+monitor, an evaluation of the invariant expression must yield a
+``true``. The thread must also reinstate the monitored invariant before
+exiting the monitor. Therefore, evaluation of the expression must also
+yield a true at that point in execution.
+
+A trivial example might be as follows. Suppose an object has three
+values, ``v1``, ``v2``, and ``sum``. The invariant is that the third
+value is the sum of the other two. Expressed mathematically, the
+invariant is ``sum = v1 + v2``. Any modification of ``v1`` or ``v2``
+requires modification of ``sum``. Since that is a complex operation, it
+must be monitored. Furthermore, any type of access to ``sum`` must also
+be monitored to ensure that neither ``v1`` nor ``v2`` are in flux.
+
+.. note::
+
+ **Note**: Evaluation of the invariant expression is a conceptual
+ requirement and is rarely done in practice. It is valuable to
+ formally define the expression during design, write it down, and
+ adhere to it. It is also useful to implement the expression during
+ development and test it where appropriate. The thread makes an
+ absolute assertion of the expression's evaluation both on entering
+ and on exiting the monitor.
+
+Acquiring a lock is a synchronous operation. Once the lock primitive is
+called, the thread returns only when it has acquired the lock. Should
+another thread (or the same thread) already have the lock held, the
+calling thread blocks, waiting for the situation to improve. That
+blocked state is not interruptible, nor is it timed.
+
+.. _Condition_Variables:
+
+Condition Variables
+~~~~~~~~~~~~~~~~~~~
+
+Condition variables facilitate communication between threads. The
+communication available is a semantic-free notification whose context
+must be supplied by the programmer. Conditions are closely associated
+with a single monitor.
+
+The association between a condition and a monitor is established when a
+condition variable is created, and the association persists for the life
+of the condition variable. In addition, a static association exists
+between the condition and some data within the monitor. This data is
+what will be manipulated by the program under the protection of the
+monitor. A thread may wait on notification of a condition that signals
+changes in the state of the associated data. Other threads may notify
+the condition when changes occur.
+
+Condition variables are always monitored. The relevant operations on
+conditions are always performed from within the monitor. They are used
+to communicate changes in the state of the monitored data (though still
+preserving the monitored invariant). Condition variables allow one or
+more threads to wait for a predetermined condition to exist, and they
+allow another thread to notify them when the condition occurs. Condition
+variables themselves do not carry the semantics of the state change, but
+simply provide a mechanism for indicating that something has changed. It
+is the programmer's responsibility to associate a condition with the
+state of the data.
+
+A thread may be designed to wait for a particular situation to exist in
+some monitored data. Since the nature of the situation is not an
+attribute of the condition, the program must test that itself. Since
+this testing involves the monitored data, it must be done from within
+the monitor. The wait operation atomically exits the monitor and blocks
+the calling thread in a waiting condition state. When the thread is
+resumed after the wait, it will have reentered the monitor, making
+operations on the data safe.
+
+There is a subtle interaction between the thread(s) waiting on a
+condition and those notifying it. The notification must take place
+within a monitor--the same monitor that protects the data being
+manipulated by the notifier. In pseudocode, the sequence looks like
+this:
+
+.. code::
+
+ enter(monitor);
+ ... manipulate the monitored data
+ notify(condition);
+ exit(monitor);
+
+Notifications to a condition do not accumulate. Nor is it required that
+any thread be waiting on a condition when the notification occurs. The
+design of the code that waits on a condition must take these facts into
+account. Therefore, the pseudocode for the waiting thread might look
+like this:
+
+.. code::
+
+ enter(monitor)
+ while (!expression) wait(condition);
+ ... manipulate monitored data
+ exit(monitor);
+
+The need to evaluate the Boolean expression again after rescheduling
+from a wait may appear unnecessary, but it is vital to the correct
+execution of the program. The notification promotes a thread waiting on
+a condition to a ready state. When that thread actually gets scheduled
+is determined by the thread scheduler and cannot be predicted. If
+multiple threads are actually processing the notifications, one or more
+of them could be scheduled ahead of the one explicitly promoted by the
+notification. One such thread could enter the monitor and perform the
+work indicated by the notification, and exit. In this case the thread
+would resume from the wait only to find that there's nothing to do.
+
+For example, suppose the defined rule of a function is that it should
+wait until there is an object available and that it should return a
+reference to that object. Writing the code as follows could potentially
+return a null reference, violating the invariant of the function:
+
+.. code::
+
+ void *dequeue()
+ {
+ void *db;
+ enter(monitor);
+ if ((db = delink()) == null)
+ {
+ wait(condition);
+ db = delink();
+ }
+ exit(monitor);
+ return db;
+ }
+
+The same function would be more appropriately written as follows:
+
+.. code::
+
+ void *dequeue()
+ {
+ void *db;
+ enter(monitor);
+ while ((db = delink()) == null)
+ wait(condition);
+ exit(monitor);
+ return db;
+ }
+
+.. note::
+
+ **Caution**: The semantics of :ref:`PR_WaitCondVar` assume that the
+ monitor is about to be exited. This assumption implies that the
+ monitored invariant must be reinstated before calling
+ :ref:`PR_WaitCondVar`. Failure to do this will cause subtle but painful
+ bugs.
+
+To modify monitored data safely, a thread must be in the monitor. Since
+no other thread may modify or (in most cases) even observe the protected
+data from outside the monitor, the thread can safely make any
+modifications needed. When the changes have been completed, the thread
+notifies the condition associated with the data and exits the monitor
+using :ref:`PR_NotifyCondVar`. Logically, each such notification promotes
+one thread that was waiting on the condition to a ready state. An
+alternate form of notification (:ref:`PR_NotifyAllCondVar`) promotes all
+threads waiting on a condition to the ready state. If no threads were
+waiting, the notification is a no-op.
+
+Waiting on a condition variable is an interruptible operation. Another
+thread could target the waiting thread and issue a :ref:`PR_Interrupt`,
+causing a waiting thread to resume. In such cases the return from the
+wait operation indicates a failure and definitively indicates that the
+cause of the failure is an interrupt.
+
+A call to :ref:`PR_WaitCondVar` may also resume because the interval
+specified on the wait call has expired. However, this fact cannot be
+unambiguously delivered, so no attempt is made to do so. If the logic of
+a program allows for timing of waits on conditions, then the clock must
+be treated as part of the monitored data and the amount of time elapsed
+re-asserted when the call returns. Philosophically, timeouts should be
+treated as explicit notifications, and therefore require the testing of
+the monitored data upon resumption.

+NSPR Logging
+============
+
+This chapter describes the global functions you use to perform logging.
+NSPR provides a set of logging functions that conditionally write
+``printf()`` style strings to the console or to a log file. NSPR uses
+this facility itself for its own development debugging purposes.
+
+You can select events to be logged by module or level. A module is a
+user-defined class of log events. A level is a numeric value that
+indicates the seriousness of the event to be logged. You can combine
+module and level criteria to get highly selective logging.
+
+NSPR also provides "assert"-style macros and functions to aid in
+application debugging.

+
+Conditional Compilation and Execution
+-------------------------------------
+
+NSPR's logging facility is conditionally compiled in and enabled for
+applications using it. These controls are platform dependent. Logging is
+not compiled in for the Win16 platform. Logging is compiled into the
+NSPR debug builds; logging is not compiled into the NSPR optimized
+builds. The compile time ``#define`` values ``DEBUG`` or
+``FORCE_PR_LOG`` enable NSPR logging for application programs.
+
+To enable NSPR logging and/or the debugging aids in your application,
+compile using the NSPR debug build headers and runtime. Set one of the
+compile-time defines when you build your application.
+
+Execution-time control of NSPR's logging uses two environment variables.
+These variables control which modules and levels are logged as well as
+the file name of the log file. By default, no logging is enabled at
+execution time.
+
+.. _Log_Types_and_Variables:

+-----------------------
+
+Two types supporting NSPR logging are exposed in the API:
+
+ - :ref:`PRLogModuleInfo`

+time:
+
+ - :ref:`NSPR_LOG_MODULES`

+Long Long integers
+==================
+
+This chapter describes the global functions you use to perform 64-bit
+integer operations. The functions define a portable API that can be used
+reliably in any environment. Where 64-bit integers are desired, use of
+NSPR's implementation is recommended to ensure cross-platform
+compatibility.
+
+Most of the 64-bit integer operations are implemented as macros. The
+specific implementation of each macro depends on whether the compiler
+for the target platform supports 64-bit integers. For a specific target
+platform, if 64-bit integers are supported for that platform, define
+``HAVE_LONG_LONG`` at compile time.
+
+.. _64-Bit_Integer_Types:
+
+64-Bit Integer Types
+~~~~~~~~~~~~~~~~~~~~
+
+NSPR provides two types to represent 64-bit integers:

+- :ref:`PRInt64`
+- :ref:`PRUint64`
+
+.. _64-Bit_Integer_Functions:
+
+64-Bit Integer Functions

+Memory Allocation Functions
+---------------------------
+
+NSPR has its own heap, and these functions act on that heap. Libraries
+built on top of NSPR, such as the Netscape security libraries, use these
+functions to allocate and free memory. If you are allocating memory for
+use by such libraries or freeing memory that was allocated by such
+libraries, you must use these NSPR functions rather than the libc
+equivalents.
+
+Memory allocation functions are:
+
+ - :ref:`PR_Malloc`
+ - :ref:`PR_Calloc`
+ - :ref:`PR_Realloc`
+ - :ref:`PR_Free`
+
+``PR_Malloc()``, ``PR_Calloc()``, ``PR_Realloc()``, and ``PR_Free()``
+have the same signatures as their libc equivalents ``malloc()``,
+``calloc()``, ``realloc()``, and ``free()``, and have the same
+semantics. (Note that the argument type ``size_t`` is replaced by
+:ref:`PRUint32`.) Memory allocated by ``PR_Malloc()``, ``PR_Calloc()``, or
+``PR_Realloc()`` must be freed by ``PR_Free()``.
+
+.. _Memory_Allocation_Macros:
+
+Memory Allocation Macros
+------------------------
+
+Macro versions of the memory allocation functions are available, as well
+as additional macros that provide programming convenience:

+In addition to the mutex type :ref:`PRLock`, NSPR provides a special type,
+:ref:`PRMonitor`, for use in Java programming. This chapter describes the
+NSPR API for creation and manipulation of a mutex of type :ref:`PRMonitor`.
+
+- `Monitor Type <#Monitor_Type>`__
+- `Monitor Functions <#Monitor_Functions>`__
+
+With a mutex of type :ref:`PRLock`, a single thread may enter the monitor
+only once before it exits, and the mutex can have multiple associated
+condition variables.
+
+With a mutex of type :ref:`PRMonitor`, a single thread may re-enter a
+monitor as many times as it sees fit. The first time the thread enters a
+monitor, it acquires the monitor's lock and the thread's entry count is
+incremented to 1. Each subsequent time the thread successfully enters
+the same monitor, the thread's entry count is incremented again, and
+each time the thread exits the monitor, the thread's entry count is
+decremented. When the entry count for a thread reaches zero, the thread
+releases the monitor's lock, and other threads that were blocked while
+trying to enter the monitor will be rescheduled.
+
+A call to :ref:`PR_Wait` temporarily returns the entry count to zero. When
+the calling thread resumes, it has the same entry count it had before
+the wait operation.
+
+Unlike a mutex of type :ref:`PRLock`, a mutex of type :ref:`PRMonitor` has a
+single, implicitly associated condition variable that may be used to
+facilitate synchronization of threads with the change in state of
+monitored data.
+
+For an introduction to NSPR thread synchronization, including locks and
+condition variables, see `Introduction to
+NSPR <Introduction_to_NSPR>`__.

+-----------------
+
+All monitor functions are thread-safe. However, this safety does not

+The chapter describes the NSPR API for named shared memory. Shared

+interface that is modeled on similar constructs in the Unix and Windows

+
+Shared Memory Protocol
+----------------------
+
+.. _Using_Named_Shared_Memory_Functions:
+
+Using Named Shared Memory Functions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+:ref:`PR_OpenSharedMemory` creates the shared memory segment, if it does
+not already exist, or opens a connection with the existing shared memory
+segment if it already exists.
+
+:ref:`PR_AttachSharedMemory` should be called following
+:ref:`PR_OpenSharedMemory` to map the memory segment to an address in the
+application's address space. :ref:`PR_AttachSharedMemory` may also be
+called to remap a shared memory segment after detaching the same
+``PRSharedMemory`` object. Be sure to detach it when you're finished.
+
+:ref:`PR_DetachSharedMemory` should be called to unmap the shared memory
+segment from the application's address space.
+
+:ref:`PR_CloseSharedMemory` should be called when no further use of the
+``PRSharedMemory`` object is required within a process. Following a call
+to :ref:`PR_CloseSharedMemory`, the ``PRSharedMemory`` object is invalid
+and cannot be reused.
+
+:ref:`PR_DeleteSharedMemory` should be called before process termination.
+After you call :ref:`PR_DeleteSharedMemory`, any further use of the shared
+memory associated with the name may cause unpredictable results.
+
+Filenames
+~~~~~~~~~
+
+The name passed to :ref:`PR_OpenSharedMemory` should be a valid filename
+for a Unix platform. :ref:`PR_OpenSharedMemory` creates file using the name
+passed in. Some platforms may mangle the name before creating the file
+and the shared memory. The Unix implementation may use SysV IPC shared
+memory, Posix shared memory, or memory mapped files; the filename may be
+used to define the namespace. On Windows, the name is significant, but
+there is no file associated with the name.
+
+No assumptions about the persistence of data in the named file should be
+made. Depending on platform, the shared memory may be mapped onto system
+paging space and be discarded at process termination.
+
+All names provided to :ref:`PR_OpenSharedMemory` should be valid filename
+syntax or name syntax for shared memory for the target platform.
+Referenced directories should have permissions appropriate for writing.
+
+.. _Limits_on_Shared_Memory_Resources:
+
+Limits on Shared Memory Resources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Different platforms have limits on both the number and size of shared
+memory resources. The default system limits on some platforms may be
+smaller than your requirements. These limits may be adjusted on some
+platforms either via boot-time options or by setting the size of the
+system paging space to accommodate more and/or larger shared memory
+segment(s).
+
+.. _Security_Considerations:
+
+Security Considerations
+~~~~~~~~~~~~~~~~~~~~~~~
+
+On Unix platforms, depending on implementation, contents of the backing
+store for the shared memory can be exposed via the file system. Set
+permissions and or access controls at create and attach time to ensure
+you get the desired security.
+
+On Windows platforms, no special security measures are provided.

+*level* is a numeric value between 0 and 5, with the values having the
+following meanings:
+
+- 0 = PR_LOG_NONE: nothing should be logged
+- 1 = PR_LOG_ALWAYS: important; intended to always be logged
+- 2 = PR_LOG_ERROR: errors
+- 3 = PR_LOG_WARNING: warnings
+- 4 = PR_LOG_DEBUG: debug messages, notices
+- 5: everything!
+
+
+Description
+-----------
+
+Specify a ``moduleName`` that is associated with the ``name`` argument
+in a call to
+`:ref:`PR_NewLogModule` <http://www-archive.mozilla.org/projects/nspr/reference/html/prlog.html#25372>`__
+and a non-zero ``level`` value to enable logging for the named
+``moduleName``.
+
+Special log module names are provided for controlling NSPR's log service
+at execution time. These controls should be set in the
+:ref:`NSPR_LOG_MODULES` environment variable at execution time to affect
+NSPR's log service for your application.
+
+- **all** The name ``all`` enables all log modules. To enable all log
+ module calls to
+ ```PR_LOG`` <http://www-archive.mozilla.org/projects/nspr/reference/html/prlog.html#25497>`__,
+ set the variable as follows:
+
+ ::
+
+ set NSPR_LOG_MODULES=all:5
+
+- **timestamp** Including ``timestamp`` results in a timestamp of the
+ form "2015-01-15 21:24:26.049906 UTC - " prefixing every logged line.
+
+- **append** Including ``append`` results in log entries being appended
+ to the existing contents of the file referenced by NSPR_LOG_FILE. If
+ not specified, the existing contents of NSPR_LOG_FILE will be lost as
+ a new file is created with the same filename.
+
+- **sync** The name ``sync`` enables unbuffered logging. This ensures
+ that all log messages are flushed to the operating system as they are
+ written, but may slow the program down.
+
+- **bufsize:size** The name ``bufsize:``\ *size* sets the log buffer to
+ *size*.
+
+Examples
+--------
+
+Log everything from the Toolkit::Storage component that happens,
+prefixing each line with the timestamp when it was logged to the file
+/tmp/foo.log (which will be replaced each time the executable is run).
+
+::
+
+ set NSPR_LOG_MODULES=timestamp,mozStorage:5
+ set NSPR_LOG_FILE=/tmp/foo.log
+
+.. _Logging_with_Try_Server:
+
+Logging with Try Server
+-----------------------
+
+- For **mochitest**, edit variable :ref:`NSPR_LOG_MODULES` in
+ ``testing/mochitest/runtests.py`` before pushing to try. You would be
+ able to download the log file as an artifact from the Log viewer.
+- (other tests?)

+This chapter describes the most common NSPR types. Other chapters
+describe more specialized types when describing the functions that use
+them.
+
+- `Calling Convention Types <#Calling_Convention_Types>`__ are used for
+ externally visible functions and globals.
+- `Algebraic Types <#Algebraic_Types>`__ of various lengths are used
+ for integer algebra.
+- `Miscellaneous Types <#Miscellaneous_Types>`__ are used for
+ representing size, pointer difference, Boolean values, and return
+ values.
+
+For information on naming conventions for NSPR types, functions, and
+macros, see `NSPR Naming
+Conventions <Introduction_to_NSPR#NSPR_Naming_Conventions>`__.
+
+.. _Calling_Convention_Types:
+
+Calling Convention Types
+------------------------
+
+These types are used to support cross-platform declarations of
+prototypes and implementations:
+
+ - :ref:`PR_EXTERN` is used for declarations of external functions or
+ variables.
+ - :ref:`PR_IMPLEMENT` is used for definitions of external functions or
+ variables.
+ - :ref:`PR_CALLBACK` is used for definitions and declarations of functions
+ that are called via function pointers. A typical example is a
+ function implemented in an application but called from a shared
+ library.
+
+Here are some simple examples of the use of these types:
+
+.. container:: highlight
+
+ In dowhim.h:
+
+ .. code::
+
+ PR_EXTERN( void ) DoWhatIMean( void );
+
+ static void PR_CALLBACK RootFunction(void *arg);
+
+.. container:: highlight
+
+ In dowhim.c:
+
+ .. code::
+
+ PR_IMPLEMENT( void ) DoWhatIMean( void ) { return; };
+
+ PRThread *thread = PR_CreateThread(..., RootFunction, ...);
+
+.. _Algebraic_Types:
+
+Algebraic Types
+---------------
+
+NSPR provides the following type definitions with unambiguous bit widths
+for algebraic operations:
+
+- `8-, 16-, and 32-bit Integer
+ Types <#8-,_16-,_and_32-bit_Integer_Types>`__
+- `64-bit Integer Types <#64-bit_Integer_Types>`__
+- `Floating-Point Number Type <#Floating-Point_Number_Type>`__
+
+For convenience, NSPR also provides type definitions with
+platform-dependent bit widths:
+
+- `Native OS Integer Types <#Native_OS_Integer_Types>`__
+

+
+.. _64-bit_Integer_Types:
+
+64-bit Integer Types
+~~~~~~~~~~~~~~~~~~~~
+
+Different platforms treat 64-bit numeric fields in different ways. Some
+systems require emulation of 64-bit fields by using two 32-bit numeric
+fields bound in a structure. Since the types (``long long`` versus
+``struct LONGLONG``) are not type compatible, NSPR defines macros to
+manipulate 64-bit numeric fields. These macros are defined in
+``prlong.h``. Conscientious use of these macros ensures portability of
+code to all the platforms supported by NSPR and still provides optimal
+behavior on those systems that treat long long values directly.
+
+ - :ref:`PRInt64`
+ - :ref:`PRUint64`
+
+.. _Floating-Point_Number_Type:
+
+Floating-Point Number Type
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The NSPR floating-point type is always 64 bits.
+
+ - :ref:`PRFloat64`
+
+.. _Native_OS_Integer_Types:
+
+Native OS Integer Types
+~~~~~~~~~~~~~~~~~~~~~~~
+
+These types are most appropriate for automatic variables. They are
+guaranteed to be at least 16 bits, though various architectures may
+define them to be wider (for example, 32 or even 64 bits). These types
+are never valid for fields of a structure.

+
+:ref:`PL_NewHashTable` creates a new hash table. The table has at least 16

+Users of the hash table functions can provide their own memory

+
+The first argument, pool, for all four functions is a void \* pointer
+that is a piece of data for the memory allocator. Typically pool points
+to a memory pool used by the memory allocator.
+
+The ``freeEntry`` function does not need to free the value of the entry.
+If flag is ``HT_FREE_ENTRY``, the function frees the entry.

+
+Remark

+

+
+Description
+-----------
+
+:ref:`PLHashComparator` is a function type that compares two values of an
+unspecified type. It returns a nonzero value if the two values are
+equal, and 0 if the two values are not equal. :ref:`PLHashComparator`
+defines the meaning of equality for the unspecified type.
+
+For convenience, two comparator functions are provided.

+:ref:`PL_CompareValues` compares the values of the arguments v1 and v2
+numerically.
+
+
+Remark
+------
+
+The return value of :ref:`PLHashComparator` functions should be of type

+
+``PLHashEntry`` is a structure that represents an entry in the hash

+
+.. code::
+
+ const void *key;

+
+The key field is a pointer to an opaque key. The value field is a

+that can fit into a ``void *`` pointer, you can just cast the key itself
+to ``void *`` and store it in the key field. Similarly, if the value of
+an entry is an integral value that can fit into a ``void *`` pointer,
+you can cast the value itself to ``void *`` and store it in the value
+field.
+
+.. warning::
+
+ **Warning**: There are other fields in the ``PLHashEntry`` structure
+ besides key and value. These fields are for use by the hash table
+ library functions and the user should not tamper with them.

+.. code::
+
+ #include <prio.h>
+
+ PRFileDesc* PR_Accept(
+ PRFileDesc *fd,
+ PRNetAddr *addr,
+ PRIntervalTime timeout);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``fd``
+ A pointer to a :ref:`PRFileDesc` object representing the rendezvous
+ socket on which the caller is willing to accept new connections.
+``addr``
+ A pointer to a structure of type :ref:`PRNetAddr`. On output, this
+ structure contains the address of the connecting entity.
+``timeout``
+ A value of type :ref:`PRIntervalTime` specifying the time limit for
+ completion of the accept operation.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful acceptance of a connection, a pointer to a new
+ :ref:`PRFileDesc` structure representing the newly accepted connection.
+- If unsuccessful, ``NULL``. Further information can be obtained by
+ calling :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+The socket ``fd`` is a rendezvous socket that has been bound to an
+address with :ref:`PR_Bind` and is listening for connections after a call
+to :ref:`PR_Listen`. :ref:`PR_Accept` accepts the first connection from the
+queue of pending connections and creates a new socket for the newly
+accepted connection. The rendezvous socket can still be used to accept
+more connections.
+
+If the ``addr`` parameter is not ``NULL``, :ref:`PR_Accept` stores the
+address of the connecting entity in the :ref:`PRNetAddr` object pointed to
+by ``addr``.
+
+:ref:`PR_Accept` blocks the calling thread until either a new connection is
+successfully accepted or an error occurs. If the timeout parameter is
+not ``PR_INTERVAL_NO_TIMEOUT`` and no pending connection can be accepted
+before the time limit, :ref:`PR_Accept` returns ``NULL`` with the error
+code ``PR_IO_TIMEOUT_ERROR``.

+ PRIntervalTime timeout);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``listenSock``
+ A pointer to a :ref:`PRFileDesc` object representing a socket descriptor
+ that has been called with the :ref:`PR_Listen` function, also known as
+ the rendezvous socket.
+``acceptedSock``
+ A pointer to a pointer to a :ref:`PRFileDesc` object. On return,
+ ``*acceptedSock`` points to the :ref:`PRFileDesc` object for the newly
+ connected socket. This parameter is valid only if the function return
+ does not indicate failure.
+``peerAddr``
+ A pointer a pointer to a :ref:`PRNetAddr` object. On return,
+ ``peerAddr`` points to the address of the remote socket. The
+ :ref:`PRNetAddr` object that ``peerAddr`` points to will be in the
+ buffer pointed to by ``buf``. This parameter is valid only if the
+ function return does not indicate failure.
+``buf``
+ A pointer to a buffer to hold data sent by the peer and the peer's
+ address. This buffer must be large enough to receive ``amount`` bytes
+ of data and two :ref:`PRNetAddr` structures (thus allowing the runtime
+ to align the addresses as needed).
+``amount``
+ The number of bytes of data to receive. Does not include the size of
+ the :ref:`PRNetAddr` structures. If 0, no data will be read from the
+ peer.
+``timeout``
+ The timeout interval only applies to the read portion of the
+ operation. :ref:`PR_AcceptRead` blocks indefinitely until the connection
+ is accepted; the read will time out after the timeout interval
+ elapses.
+
+
+Returns
+~~~~~~~
+
+- A positive number indicates the number of bytes read from the peer.
+- The value -1 indicates a failure. The reason for the failure can be

+
+
+Description
+-----------
+
+:ref:`PR_AcceptRead` accepts a new connection and retrieves the newly
+created socket's descriptor and the connecting peer's address. Also, as

+
+The thread object is automatically destroyed when it is no longer
+needed.
+
+You don't need to call :ref:`PR_AttachThread` unless you create your own
+native thread. :ref:`PR_Init` calls :ref:`PR_AttachThread` automatically for
+the primordial thread.
+
+.. note::
+
+ **Note**: As of NSPR release v3.0, :ref:`PR_AttachThread` and
+ :ref:`PR_DetachThread` are obsolete. A native thread not created by NSPR
+ is automatically attached the first time it calls an NSPR function,
+ and automatically detached when it exits.
+
+In NSPR release 19980529B and earlier, it is necessary for a native
+thread not created by NSPR to call :ref:`PR_AttachThread` before it calls
+any NSPR functions, and call :ref:`PR_DetachThread` when it is done calling

+PR_Available64
+==============
+
+Determines the number of bytes (expressed as a 32-bit integer) that are
+available for reading beyond the current read-write pointer in a
+specified file or socket.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prio.h>
+
+ PRInt64 PR_Available64(PRFileDesc *fd);
+
+
+Parameter
+~~~~~~~~~
+
+The function has the following parameter:
+
+``fd``
+ Pointer to a :ref:`PRFileDesc` object representing a file or socket.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If the function completes successfully, it returns the number of
+ bytes that are available for reading. For a normal file, these are
+ the bytes beyond the current file pointer.
+- If the function fails, it returns the value -1. The error code can
+ then be retrieved via :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+:ref:`PR_Available64` works on normal files and sockets. :ref:`PR_Available`
+does not work with pipes on Win32 platforms.
+
+
+See Also
+--------
+
+If the number of bytes available for reading is within the range of a

+
+.. code::
+
+ #include <prio.h>
+
+ PRStatus PR_Bind(
+ PRFileDesc *fd,
+ const PRNetAddr *addr);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``fd``
+ A pointer to a :ref:`PRFileDesc` object representing a socket.
+``addr``
+ A pointer to a :ref:`PRNetAddr` object representing the address to which
+ the socket will be bound.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful binding of an address to a socket, ``PR_SUCCESS``.
+- If unsuccessful, ``PR_FAILURE``. Further information can be obtained
+ by calling :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+When a new socket is created, it has no address bound to it. :ref:`PR_Bind`
+assigns the specified address (also known as name) to the socket. If you
+do not care about the exact IP address assigned to the socket, set the
+``inet.ip`` field of :ref:`PRNetAddr` to :ref:`PR_htonl`\ (``PR_INADDR_ANY``).
+If you do not care about the TCP/UDP port assigned to the socket, set
+the ``inet.port`` field of :ref:`PRNetAddr` to 0.
+
+Note that if :ref:`PR_Connect` is invoked on a socket that is not bound, it
+implicitly binds an arbitrary address the socket.
+
+Call :ref:`PR_GetSockName` to obtain the address (name) bound to a socket.

+Syntax
+------
+
+.. code::

+
+ PRMonitor* PR_CEnterMonitor(void *address);
+
+
+Parameter
+~~~~~~~~~
+
+The function has the following parameter:
+
+``address``
+ A reference to the data that is to be protected by the monitor. This
+ reference must remain valid as long as there are monitoring
+ operations being performed.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If successful, the function returns a pointer to the :ref:`PRMonitor`
+ associated with the value specified in the ``address`` parameter.
+- If unsuccessful (the monitor cache needs to be expanded and the
+ system is out of memory), the function returns ``NULL``.
+
+
+Description
+-----------
+
+:ref:`PR_CEnterMonitor` uses the value specified in the ``address``
+parameter to find a monitor in the monitor cache, then enters the lock
+associated with the monitor. If no match is found, an available monitor
+is associated with the address and the monitor's entry count is
+incremented (so it has a value of one). If a match is found, then either
+the calling thread is already in the monitor (and this is a reentrant
+call) or another thread is holding the monitor's mutex. In the former
+case, the entry count is simply incremented and the function returns. In
+the latter case, the calling thread is likely to find the monitor locked
+by another thread and waits for that thread to exit before continuing.
+
+.. note::
+
+ **Note**: :ref:`PR_CEnterMonitor` and :ref:`PR_CExitMonitor` must be
+ paired--that is, there must be an exit for every entry--or the object
+ will never become available for any other thread.

+PR_ClearInterrupt
+=================

+
+
+Syntax
+------
+
+.. code::
+
+ #include <prthread.h>
+
+ void PR_ClearInterrupt(void);

+
+Description
+-----------
+
+Interrupting is a cooperative process, so it's possible that the thread
+passed to :ref:`PR_Interrupt` may never respond to the interrupt request.
+For example, the target thread may reach the agreed-on control point
+without providing an opportunity for the runtime to notify the thread of
+the interrupt request. In this case, the request for interrupt is still
+pending with the thread and must be explicitly canceled. Therefore it is
+sometimes necessary to call :ref:`PR_ClearInterrupt` to clear a previous
+interrupt request.
+
+If no interrupt request is pending, :ref:`PR_ClearInterrupt` is a no-op.

+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``fd``
+ A pointer to a :ref:`PRFileDesc` object representing a socket.
+``addr``
+ A pointer to the address of the peer to which the socket is to be
+ connected.
+``timeout``
+ A value of type :ref:`PRIntervalTime` specifying the time limit for
+ completion of the connect operation.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful completion of connection setup, ``PR_SUCCESS``.
+- If unsuccessful, ``PR_FAILURE``. Further information can be obtained
+ by calling :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+:ref:`PR_Connect` is usually invoked on a TCP socket, but it may also be
+invoked on a UDP socket. Both cases are discussed here.
+
+If the socket is a TCP socket, :ref:`PR_Connect` establishes a TCP
+connection to the peer. If the socket is not bound, it will be bound to
+an arbitrary local address.
+
+:ref:`PR_Connect` blocks until either the connection is successfully
+established or an error occurs. The function uses the lesser of the
+provided timeout and the OS's connect timeout. In particular, if you
+specify ``PR_INTERVAL_NO_TIMEOUT`` as the timeout, the OS's connection
+time limit will be used.
+
+If the socket is a UDP socket, there is no connection setup to speak of,
+since UDP is connectionless. If :ref:`PR_Connect` is invoked on a UDP
+socket, it has an overloaded meaning: :ref:`PR_Connect` merely saves the
+specified address as the default peer address for the socket, so that
+subsequently one can send and receive datagrams from the socket using
+:ref:`PR_Send` and :ref:`PR_Recv` instead of the usual :ref:`PR_SendTo` and
+:ref:`PR_RecvFrom`.

+``fd``
+ A pointer to a :ref:`PRFileDesc` object representing a socket.
+
+``out_flags``
+ The out_flags field of the poll descriptor returned by
+ `PR_Poll() <PR_Poll>`__.
+
+
+Returns
+~~~~~~~
+
+- If the nonblocking connect has successfully completed,
+ PR_ConnectContinue returns PR_SUCCESS.
+- If PR_ConnectContinue() returns PR_FAILURE, call PR_GetError():
+- PR_IN_PROGRESS_ERROR: the nonblocking connect is still in
+ progress and has not completed yet. The caller should poll the file
+ descriptor for the in_flags PR_POLL_WRITE|PR_POLL_EXCEPT and retry
+ PR_ConnectContinue later when PR_Poll() returns.

+
+
+Description
+-----------
+
+Continue a nonblocking connect. After a nonblocking connect is initiated
+with PR_Connect() (which fails with PR_IN_PROGRESS_ERROR), one should
+call PR_Poll() on the socket, with the in_flags PR_POLL_WRITE \|
+PR_POLL_EXCEPT. When PR_Poll() returns, one calls PR_ConnectContinue()
+on the socket to determine whether the nonblocking connect has completed
+or is still in progress. Repeat the PR_Poll(), PR_ConnectContinue()
+sequence until the nonblocking connect has completed.

+PR_CWait
+========

+Syntax
+------
+
+.. code::
+
+ #include <prcmon.h>
+
+ PRStatus PR_CWait(
+ void *address,
+ PRIntervalTime timeout);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``address``
+ The address of the protected object--the same address previously
+ passed to :ref:`PR_CEnterMonitor`.
+``timeout``
+ The amount of time (in :ref:`PRIntervalTime` units) that the thread is
+ willing to wait for an explicit notification before being
+ rescheduled. If you specify ``PR_INTERVAL_NO_TIMEOUT``, the function
+ returns if and only if the object is notified.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+ - :ref:`PR_SUCCESS` indicates either that the monitored object has been
+ notified or that the interval specified in the timeout parameter has
+ been exceeded.
+ - :ref:`PR_FAILURE` indicates either that the monitor could not be located
+ in the cache or that the monitor was located and the calling thread
+ was not the thread that held the monitor's mutex.
+
+
+Description
+-----------
+
+Using the value specified in the ``address`` parameter to find a monitor
+in the monitor cache, :ref:`PR_CWait` waits for a notification that the
+monitor's state has changed. While the thread is waiting, it exits the
+monitor (just as if it had called :ref:`PR_CExitMonitor` as many times as
+it had called :ref:`PR_CEnterMonitor`). When the wait has finished, the
+thread regains control of the monitor's lock with the same entry count
+as before the wait began.
+
+The thread waiting on the monitor resumes execution when the monitor is
+notified (assuming the thread is the next in line to receive the notify)
+or when the interval specified in the ``timeout`` parameter has been
+exceeded. When the thread resumes execution, it is the caller's
+responsibility to test the state of the monitored data to determine the
+appropriate action.

+
+This function detaches the NSPR thread from the currently executing
+native thread. The thread object and all related data attached to it are
+destroyed. The exit process is invoked. The call returns after the NSPR
+thread object is destroyed.
+
+This call is needed only if you attached the thread using
+:ref:`PR_AttachThread`.
+
+.. note::
+
+ **Note**: As of NSPR release v3.0, :ref:`PR_AttachThread` and
+ :ref:`PR_DetachThread` are obsolete. A native thread not created by NSPR
+ is automatically attached the first time it calls an NSPR function,
+ and automatically detached when it exits.
+
+In NSPR release 19980529B and earlier, it is necessary for a native
+thread not created by NSPR to call :ref:`PR_AttachThread` before it calls
+any NSPR functions, and call :ref:`PR_DetachThread` when it is done calling
+NSPR functions.

+
+
+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+``d``
+ The floating point number to be converted to a string.
+``mode``
+ The type of conversion to employ.
+``ndigits``
+ The number of digits desired in the output string.
+``decpt``
+ A pointer to a memory location where the runtime will store the
+ offset, relative to the beginning of the output string, of the
+ conversion's decimal point.
+``sign``
+ A location where the runtime can store an indication that the
+ conversion was of a negative value.
+``*rve``
+ If not ``NULL`` this location is set to the address of the end of the
+ result.
+``buf``
+ The address of the buffer in which to store the result.
+``bufsz``
+ The size of the buffer provided to hold the result.
+
+Results
+~~~~~~~
+
+The principle output is the null-terminated string stored in ``buf``. If
+``rve`` is not ``NULL``, ``*rve`` is set to point to the end of the
+returned value.
+
+
+Description
+-----------
+
+This function converts the specified floating point number to a string,
+using the method specified by ``mode``. Possible modes are:
+
+``0``
+ Shortest string that yields ``d`` when read in and rounded to
+ nearest.
+``1``
+ Like 0, but with Steele & White stopping rule. For example, with IEEE
+ 754 arithmetic, mode 0 gives 1e23 whereas mode 1 gives
+ 9.999999999999999e22.
+``2``
+ ``max(1, ndigits)`` significant digits. This gives a return value
+ similar to that of ``ecvt``, except that trailing zeros are
+ suppressed.
+``3``
+ Through ``ndigits`` past the decimal point. This gives a return value
+ similar to that from ``fcvt``, except that trailing zeros are
+ suppressed, and ``ndigits`` can be negative.
+``4,5,8,9``
+ Same as modes 2 and 3, but using\ *left to right* digit generation.
+``6-9``
+ Same as modes 2 and 3, but do not try fast floating-point estimate
+ (if applicable).
+``all others``
+ Treated as mode 2.
+
+Upon return, the buffer specified by ``buf`` and ``bufsz`` contains the
+converted string. Trailing zeros are suppressed. Sufficient space is
+allocated to the return value to hold the suppressed trailing zeros.
+
+If the input parameter ``d`` is\ *+Infinity*,\ *-Infinity* or\ *NAN*,
+``*decpt`` is set to 9999.

+Parameter
+~~~~~~~~~
+
+The function has the following parameter:
+
+``mon``
+ A reference to an existing structure of type :ref:`PRMonitor`.
+
+
+Description
+-----------
+
+When the calling thread returns, it will have acquired the monitor's
+lock. Attempts to acquire the lock for a monitor that is held by some
+other thread will result in the caller blocking. The operation is
+neither timed nor interruptible.
+
+If the monitor's entry count is greater than zero and the calling thread
+is recognized as the holder of the lock, :ref:`PR_EnterMonitor` increments
+the entry count by one and returns. If the entry count is greater than
+zero and the calling thread is not recognized as the holder of the lock,
+the thread is blocked until the entry count reaches zero. When the entry
+count reaches zero (or if it is already zero), the entry count is
+incremented by one and the calling thread is recorded as the lock's
+holder.

+indicate that the connection has failed.
+
+
+Description
+-----------
+
+After :ref:`PR_Connect` on a nonblocking socket fails with
+``PR_IN_PROGRESS_ERROR``, you may wait for the connection to complete by
+calling :ref:`PR_Poll` on the socket with the ``in_flags``

+.. code::
+
+ #include <prio.h>
+
+ PRStatus PR_GetOpenFileInfo64(
+ PRFileDesc *fd,
+ PRFileInfo *info);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``fd``
+ A pointer to a :ref:`PRFileDesc` object for an open file.
+``info``
+ A pointer to a :ref:`PRFileInfo64` object. On output, information about
+ the given file is written into the file information object.

+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If file information is successfully obtained, ``PR_SUCCESS``.
+- If file information is not successfully obtained, ``PR_FAILURE``.
+
+
+Description
+-----------
+
+:ref:`PR_GetOpenFileInfo64` is the 64-bit version of
+:ref:`PR_GetOpenFileInfo`. It obtains the file type (normal file,
+directory, or other), file size (as a 64-bit integer), and the creation
+and modification times of the open file represented by the file
+descriptor.
+
+
+See Also
+--------
+
+For the 32-bit version of this function, see :ref:`PR_GetOpenFileInfo`. To
+get equivalent information on a file that's not already open, use
+:ref:`PR_GetFileInfo64`.

+Description
+-----------
+
+Used for platform-specific code that requires the underlying OS error.
+For portability, clients should not create dependencies on the values of
+OS-specific error codes. However, this information is preserved, along
+with a platform neutral error code, on a per thread basis. It is most
+useful during development.

+ The size, in bytes, of the requested random number.
+

+Returns
+~~~~~~~
+
+:ref:`PRSize` value equal to the size of the random number actually

+
+:ref:`PR_GetRandomNoise` provides a random value, depending on platform.

+PR_ImportTCPSocket
+==================
+

+
+Syntax
+------
+
+.. code::
+
+ #include "private/pprio.h"
+
+ PRFileDesc* PR_ImportTCPSocket(PROsfd osfd);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``osfd``
+ The native file descriptor for the TCP socket to import. On POSIX
+ systems, this is an ``int``. On Windows, this is a ``SOCKET``.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful completion, a pointer to the :ref:`PRFileDesc` object
+ created for the newly imported native TCP socket.
+- If the import of the native TCP socket failed, ``NULL``.
+
+
+Description
+-----------
+
+A native TCP socket ``osfd`` can be imported into NSPR with
+:ref:`PR_ImportTCPSocket`. The caller gives up control of the native TCP
+socket ``osfd`` and should use the ``PRFileDesc*`` returned by
+:ref:`PR_ImportTCPSocket` instead.
+
+Although :ref:`PR_ImportTCPSocket` is a supported function, it is declared
+in ``"private/pprio.h"`` to stress the fact that this function depends
+on the internals of the NSPR implementation. The caller needs to
+understand what NSPR will do to the native file descriptor and make sure
+that NSPR can use the native file descriptor successfully.
+
+For example, on POSIX systems, NSPR will put the native file descriptor
+(an ``int``) in non-blocking mode by calling ``fcntl`` to set the
+``O_NONBLOCK`` file status flag on the native file descriptor, and then
+NSPR will call socket functions such as ``recv``, ``send``, and ``poll``
+on the native file descriptor. The caller must not do anything to the

+prevent the native file descriptor from working in non-blocking mode.
+
+Warning
+-------
+
+In theory, code that uses :ref:`PR_ImportTCPSocket` may break when NSPR's
+implementation changes. In practice, this is unlikely to happen because
+NSPR's implementation has been stable for years and because of NSPR's
+strong commitment to backward compatibility. Using
+:ref:`PR_ImportTCPSocket` is much more convenient than writing an NSPR I/O
+layer that wraps your native TCP sockets. Of course, it is best if you
+just use :ref:`PR_OpenTCPSocket` or :ref:`PR_NewTCPSocket`. If you are not
+sure whether :ref:`PR_ImportTCPSocket` is right for you, please ask in the
+mozilla.dev.tech.nspr newsgroup.

+
+
+Parameters
+~~~~~~~~~~
+
+:ref:`PR_Initialize` has the following parameters:
+

+ The function that becomes the primordial thread's root function.
+ Returning from prmain leads to termination of the process.
+``argc``
+ The length of the argument vector, whether passed in from the host's

+
+The value returned from the root function, ``prmain``.
+
+
+Description
+-----------
+
+:ref:`PR_Initialize` initializes the NSPR runtime and places NSPR between

+allowing the runtime to coordinate the completion of the other threads
+of the runtime.
+
+:ref:`PR_Initialize` does not return to its caller until all user threads
+have terminated.
+
+The priority of the main (or primordial) thread is
+``PR_PRIORITY_NORMAL``. The thread may adjust its own priority by using

+

+
+ PRStatus PR_InitializeNetAddr(
+ PRNetAddrValue val,
+ PRUint16 port,

+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``val``
+ The value to be assigned to the IP Address portion of the network
+ address. This must be ``PR_IpAddrNull``, ``PR_IpAddrAny``, or
+ ``PR_IpAddrLoopback``.
+``port``
+ The port number to be assigned in the network address structure. The
+ value is specified in host byte order.
+``addr``
+ A pointer to the :ref:`PRNetAddr` structure to be manipulated.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If successful, ``PR_SUCCESS``.
+- If unsuccessful, ``PR_FAILURE``. This may occur, for example, if the
+ value of val is not within the ranges defined by ``PRNetAddrValue``.
+ You can retrieve the reason for the failure by calling
+ :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+:ref:`PR_InitializeNetAddr` allows the assignment of special network
+address values and the port number, while also setting the state that
+indicates the version of the address being used.
+
+The special network address values are identified by the enum
+``PRNetAddrValue``:
+
+.. code::
+
+ typedef enum PRNetAddrValue{
+ PR_IpAddrNull,
+ PR_IpAddrAny,
+ PR_IpAddrLoopback
+ } PRNetAddrValue;
+
+The enum has the following enumerators:
+
+``PR_IpAddrNull``
+ Do not overwrite the IP address. This allows the caller to change the
+ network address' port number assignment without affecting the host
+ address.
+``PR_IpAddrAny``
+ Assign logical ``PR_INADDR_ANY`` to IP address. This wildcard value
+ is typically used to establish a socket on which to listen for
+ incoming connection requests.
+``PR_IpAddrLoopback``
+ Assign logical ``PR_INADDR_LOOPBACK``. A client can use this value to
+ connect to itself without knowing the host's network address.

+PR_Interrupt
+============
+
+Sets the interrupt request for a target thread.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prthread.h>
+
+ PRStatus PR_Interrupt(PRThread *thread);
+
+
+Parameter
+~~~~~~~~~
+
+:ref:`PR_Interrupt` has the following parameter:
+
+``thread``
+ The thread whose interrupt request you want to set.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If the specified thread is currently blocked, ``PR_SUCCESS``.
+- Otherwise, ``PR_FAILURE``.
+
+
+Description
+-----------
+
+The purpose of :ref:`PR_Interrupt` is to request that a thread performing
+some task stop what it is doing and return to some control point. It is
+assumed that a control point has been mutually arranged between the
+thread doing the interrupting and the thread being interrupted. When the
+interrupted thread reaches the prearranged point, it can communicate
+with its peer to discover the real reason behind the change in plans.
+
+The interrupt request remains in the thread's state until it is
+delivered exactly once or explicitly canceled. The interrupted thread
+returns ``PR_FAILURE`` (-1) with an error code (see :ref:`PR_GetError`) for
+blocking operations that return a :ref:`PRStatus` (such as I/O operations,
+monitor waits, or waiting on a condition). To check whether the thread
+was interrupted, compare the result of :ref:`PR_GetError` with
+``PR_PENDING_INTERRUPT_ERROR``.
+
+:ref:`PR_Interrupt` may itself fail if the target thread is invalid.
+
+Bugs
+----
+
+:ref:`PR_Interrupt` has the following limitations and known bugs:
+
+- There can be a delay for a thread to be interrupted from a blocking
+ I/O function. In all NSPR implementations, the maximum delay is at
+ most five seconds. In the pthreads-based implementation on Unix, the
+ maximum delay is 0.1 seconds.
+- File I/O is considered instantaneous, so file I/O functions cannot be
+ interrupted. Unfortunately the standard input, output, and error
+ streams are treated as files by NSPR, so a :ref:`PR_Read` call on
+ ``PR_STDIN`` cannot be interrupted even though it may block
+ indefinitely.
+- In the NT implementation, :ref:`PR_Connect` cannot be interrupted.
+- In the NT implementation, a file descriptor is not usable and must be
+ closed after an I/O function on the file descriptor is interrupted.

+

+Returns
+~~~~~~~
+
+A :ref:`PRIntervalTime` object.
+
+
+Description
+-----------
+
+You can use the value returned by ``PR_IntervalNow()`` to establish
+epochs and to determine intervals (that is, compute the difference
+between two times). ``PR_IntervalNow()`` is both very efficient and
+nonblocking, so it is appropriate to use (for example) while holding a
+mutex.
+
+The most common use for ``PR_IntervalNow()`` is to establish an epoch
+and test for the expiration of intervals. In this case, you typically
+call ``PR_IntervalNow()`` in a sequence that looks like this:
+
+.. code::
+
+ PRUint32 interval = ... ; // milliseconds
+ // ...
+ PRStatus rv;
+ PRIntervalTime epoch = PR_IntervalNow();
+ PR_Lock(data->mutex);

+ if (delta > interval) break; /* timeout */
+ rv = PR_Wait(data->condition, PR_MillisecondsToInterval(interval - delta));
+ if (PR_FAILURE == rv) break; /* likely an interrupt */
+ }
+ PR_Unlock(data->mutex);

+
+Syntax

+ PRFileDesc* PR_NewTCPSocket(void);

+
+The function returns one of the following values:

+- Upon successful completion, a pointer to the :ref:`PRFileDesc` object
+ created for the newly opened IPv4 TCP socket.
+- If the creation of a new TCP socket failed, ``NULL``.
+
+
+Description
+-----------
+
+TCP (Transmission Control Protocol) is a connection-oriented, reliable
+byte-stream protocol of the TCP/IP protocol suite. :ref:`PR_NewTCPSocket`
+creates a new IPv4 TCP socket. A TCP connection is established by a
+passive socket (the server) accepting a connection setup request from an
+active socket (the client). Typically, the server binds its socket to a
+well-known port with :ref:`PR_Bind`, calls :ref:`PR_Listen` to start listening
+for connection setup requests, and calls :ref:`PR_Accept` to accept a
+connection. The client makes a connection request using :ref:`PR_Connect`.
+
+After a connection is established, the client and server may send and
+receive data between each other. To receive data, one can call
+:ref:`PR_Read` or :ref:`PR_Recv`. To send data, one can call :ref:`PR_Write`,
+:ref:`PR_Writev`, :ref:`PR_Send`, or :ref:`PR_TransmitFile`. :ref:`PR_AcceptRead` is
+suitable for use by the server to accept a new client connection and
+read the client's first request in one function call.
+
+A TCP connection can be shut down by :ref:`PR_Shutdown`, and the sockets
+should be closed by :ref:`PR_Close`.
+
+
+See Also
+--------
+
+:ref:`PR_NewTCPSocket` is deprecated because it is hardcoded to create an
+IPv4 TCP socket. New code should use :ref:`PR_OpenTCPSocket` instead, which
+allows the address family (IPv4 or IPv6) of the new TCP socket to be
+specified.

+PR_NewThreadPrivateIndex
+========================
+
+Returns a new index for a per-thread private data table and optionally

+Syntax
+------
+
+.. code::

+ #include <prthread.h>

+ PRStatus PR_NewThreadPrivateIndex(
+ PRUintn *newIndex,
+ PRThreadPrivateDTOR destructor);
+
+
+Parameters
+~~~~~~~~~~
+
+:ref:`PR_NewThreadPrivateIndex` has the following parameters:
+
+``newIndex``
+ On output, an index that is valid for all threads in the process. You
+ use this index with :ref:`PR_SetThreadPrivate` and
+ :ref:`PR_GetThreadPrivate`.
+``destructor``
+ Specifies a destructor function :ref:`PRThreadPrivateDTOR` for the
+ private data associated with the index. This function can be
+ specified as ``NULL``.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If successful, ``PR_SUCCESS``.
+- If the total number of indices exceeds 128, ``PR_FAILURE``.
+
+
+Description
+-----------
+
+If :ref:`PR_NewThreadPrivateIndex` is successful, every thread in the same
+process is capable of associating private data with the new index. Until
+the data for an index is actually set, the value of the private data at
+that index is ``NULL``. You pass this index to :ref:`PR_SetThreadPrivate`
+and :ref:`PR_GetThreadPrivate` to set and retrieve data associated with the
+index.
+
+When you allocate the index, you may also register a destructor function
+of type :ref:`PRThreadPrivateDTOR`. If a destructor function is registered
+with a new index, it will be called at one of two times, as long as the
+private data is not ``NULL``:
+
+- when replacement private data is set with :ref:`PR_SetThreadPrivate`
+- when a thread exits
+
+The index maintains independent data values for each binding thread. A
+thread can get access only to its own thread-specific data. There is no
+way to deallocate a private data index once it is allocated.

+
+Creates a new UDP socket.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prio.h>
+
+ PRFileDesc* PR_NewUDPSocket(void);
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful completion, a pointer to the :ref:`PRFileDesc` object
+ created for the newly opened UDP socket.
+- If the creation of a new UDP socket failed, ``NULL``.
+
+
+Description
+-----------
+
+UDP (User Datagram Protocol) is a connectionless, unreliable datagram
+protocol of the TCP/IP protocol suite. UDP datagrams may be lost or
+delivered in duplicates or out of sequence.
+
+:ref:`PR_NewUDPSocket` creates a new UDP socket. The socket may be bound to
+a well-known port number with :ref:`PR_Bind`. Datagrams can be sent with
+:ref:`PR_SendTo` and received with :ref:`PR_RecvFrom`. When the socket is no
+longer needed, it should be closed with a call to :ref:`PR_Close`.
+
+
+See Also
+--------
+
+:ref:`PR_NewUDPSocket` is deprecated because it is hardcoded to create an
+IPv4 UDP socket. New code should use :ref:`PR_OpenUDPSocket` instead, which
+allows the address family (IPv4 or IPv6) of the new UDP socket to be
+specified.

+PR_NormalizeTime
+================
+
+Adjusts the fields of a clock/calendar time to their proper ranges,
+using a callback function.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prtime.h>
+
+ void PR_NormalizeTime (
+ PRExplodedTime *time,
+ PRTimeParamFn params);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+``time``
+ A pointer to a clock/calendar time in the :ref:`PRExplodedTime` format.
+``params``
+ A time parameter callback function.
+
+
+Returns
+~~~~~~~
+
+Nothing; the ``time`` parameter is altered by the callback function.
+
+
+Description
+-----------
+
+This function adjusts the fields of the specified time structure using
+the specified time parameter callback function, so that they are in the
+proper range.
+
+Call this function in these situations:
+
+- To normalize a time after performing arithmetic operations directly
+ on the field values of the calendar time object. For example, if you
+ have a ``]`` object that represents the date 3 March 1998 and you
+ want to say "forty days from 3 March 1998", you can simply add 40 to
+ the ``tm_mday`` field and then call ``PR_NormalizeTime()``.
+
+- To calculate the optional field values ``tm_wday`` and ``tm_yday``.
+ For example, suppose you want to compute the day of week for 3 March
+ 1998. You can set ``tm_mday`` to 3, ``tm_month`` to 2, and
+ ``tm_year`` to 1998, and all the other fields to 0, then call
+ ``PR_NormalizeTime()`` with :ref:`PR_GMTParameters`. On return,
+ ``tm_wday`` (and ``tm_yday``) are set for you.
+
+- To convert from one time zone to another. For example, if the input
+ argument time is in time zone A and the input argument ``params``
+ represents time zone B, when ``PR_NormalizeTime()`` returns, time
+ will be in time zone B.

+
+The function has the following parameter:

+Description
+-----------
+
+Notification of a monitor signals the change of state of some monitored
+data. The changing of that data and the notification must all be
+performed while in the monitor. When the notification occurs, the
+runtime promotes a thread that is waiting on the monitor to a ready
+state. If more than one thread is waiting, the selection of which thread
+gets promoted cannot be determined in advance. This implies that all
+threads waiting on a single monitor must have the same semantics. If no
+thread is waiting on the monitor, the notify operation is a no-op.

+ #include <prio.h>
+

+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``af``
+ The address family of the new TCP socket. Can be ``PR_AF_INET``
+ (IPv4), ``PR_AF_INET6`` (IPv6), or ``PR_AF_LOCAL`` (Unix domain,

+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- Upon successful completion, a pointer to the :ref:`PRFileDesc` object
+ created for the newly opened TCP socket.
+- If the creation of a new TCP socket failed, ``NULL``.
+
+
+Description
+-----------
+
+TCP (Transmission Control Protocol) is a connection-oriented, reliable
+byte-stream protocol of the TCP/IP protocol suite. :ref:`PR_OpenTCPSocket`
+creates a new TCP socket of the address family ``af``. A TCP connection
+is established by a passive socket (the server) accepting a connection
+setup request from an active socket (the client). Typically, the server
+binds its socket to a well-known port with :ref:`PR_Bind`, calls
+:ref:`PR_Listen` to start listening for connection setup requests, and
+calls :ref:`PR_Accept` to accept a connection. The client makes a
+connection request using :ref:`PR_Connect`.
+
+After a connection is established, the client and server may send and
+receive data between each other. To receive data, one can call
+:ref:`PR_Read` or :ref:`PR_Recv`. To send data, one can call :ref:`PR_Write`,
+:ref:`PR_Writev`, :ref:`PR_Send`, or :ref:`PR_TransmitFile`. :ref:`PR_AcceptRead` is
+suitable for use by the server to accept a new client connection and
+read the client's first request in one function call.
+
+A TCP connection can be shut down by :ref:`PR_Shutdown`, and the sockets
+should be closed by :ref:`PR_Close`.

+PR_Poll
+=======
+
+Detects when I/O is ready for a set of socket file descriptors.
+

+
+ #include <prio.h>
+
+ PRInt32 PR_Poll(
+ PRPollDesc *pds,
+ PRIntn npds,
+ PRIntervalTime timeout);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``pds``
+ A pointer to the first element of an array of ``PRPollDesc``
+ structures.
+``npds``
+ The number of elements in the ``pds`` array. If this parameter is
+ zero, :ref:`PR_Poll` is equivalent to :ref:`PR_Sleep` with a timeout.
+``timeout``
+ Amount of time the call will block waiting for I/O to become ready.
+ If this time expires without any I/O becoming ready, :ref:`PR_Poll`
+ returns zero.
+
+
+Returns
+~~~~~~~
+
+The function returns one of these values:
+
+- If successful, the function returns a positive number indicating the
+ number of ``PRPollDesc`` structures in ``pds`` that have events.
+- The value 0 indicates the function timed out.
+- The value -1 indicates the function failed. The reason for the
+ failure can be obtained by calling :ref:`PR_GetError`.
+
+
+Description
+~~~~~~~~~~~
+
+This function returns as soon as I/O is ready on one or more of the
+underlying socket objects. A count of the number of ready descriptors is
+returned unless a timeout occurs, in which case zero is returned.
+
+The ``in_flags`` field of the ``PRPollDesc`` data structure should be
+set to the I/O events (readable, writable, exception, or some
+combination) that the caller is interested in. On successful return, the
+``out_flags`` field of the ``PRPollDesc`` data structure is set to
+indicate what kind of I/O is ready on the respective descriptor.
+:ref:`PR_Poll` uses the ``out_flags`` fields as scratch variables during
+the call. If :ref:`PR_Poll` returns 0 or -1, the ``out_flags`` fields do
+not contain meaningful values and must not be used.
+
+The ``PRPollDesc`` structure is defined as follows:
+
+.. code::
+
+ struct PRPollDesc {
+ PRFileDesc* fd;
+ PRInt16 in_flags;
+ PRInt16 out_flags;
+ };
+
+ typedef struct PRPollDesc PRPollDesc;
+
+The structure has the following fields:
+
+``fd``
+ A pointer to a :ref:`PRFileDesc` object representing a socket or a
+ pollable event. This field can be set to ``NULL`` to indicate to
+ :ref:`PR_Poll` that this ``PRFileDesc object`` should be ignored.
+
+ .. note::
+
+ On Unix, the ``fd`` field can be set to a pointer to any
+ :ref:`PRFileDesc` object, including one representing a file or a
+ pipe. Cross-platform applications should only set the ``fd`` field
+ to a pointer to a :ref:`PRFileDesc` object representing a socket or a
+ pollable event because on Windows the ``select`` function can only
+ be used with sockets.
+``in_flags``
+ A bitwise ``OR`` of the following bit flags:
+
+ - :ref:`PR_POLL_READ`: ``fd`` is readable.
+ - :ref:`PR_POLL_WRITE`: ``fd`` is writable.
+ - :ref:`PR_POLL_EXCEPT`: ``fd`` has an exception condition.
+
+``out_flags``
+ A bitwise ``OR`` of the following bit flags:
+
+ - :ref:`PR_POLL_READ`
+ - :ref:`PR_POLL_WRITE`
+ - :ref:`PR_POLL_EXCEPT`
+ - :ref:`PR_POLL_ERR`: ``fd`` has an error.
+ - :ref:`PR_POLL_NVAL`: ``fd`` is bad.
+
+Note that the ``PR_POLL_ERR`` and ``PR_POLL_NVAL`` flags are used only
+in ``out_flags``. The ``PR_POLL_ERR`` and ``PR_POLL_NVAL`` events are
+always reported by :ref:`PR_Poll`.

+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:

+ A pointer to a :ref:`PRFileDesc` object representing the stack from
+ which the specified layer is to be removed.
+``id``
+ Identity of the layer to be removed from the stack.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If the layer is successfully removed from the stack, a pointer to the
+ removed layer.
+- If the layer is not found in the stack or cannot be popped (for
+ example, the bottommost layer), the function returns ``NULL`` with

+
+
+Description
+-----------
+
+:ref:`PR_PopIOLayer` pops the specified layer from the stack. If the object
+to be removed is found, :ref:`PR_PopIOLayer` returns a pointer to the
+removed object The object then becomes the responsibility of the caller.
+
+Even if the identity indicates the top layer of the stack, the reference
+returned is not the file descriptor for the stack and that file
+descriptor remains valid. In other words, ``stack`` continues to point
+to the top of the stack after the function returns.

+- If the layer is not successfully pushed onto the stack,

+ regarding the reason for the failure.
+
+
+Description
+-----------
+
+A file descriptor for a layer (possibly allocated using
+:ref:`PR_CreateIOLayerStub`) may be pushed onto an existing stack of file
+descriptors at any time. The new layer is inserted into the stack just
+above the layer with the identity specified by ``id``.
+
+Even if the ``id`` parameter indicates the topmost layer of the stack,
+the value of the file descriptor describing the original stack will not
+change. In other words, ``stack`` continues to point to the top of the
+stack after the function returns.
+
+Caution
+-------
+
+Keeping the pointer to the stack even as layers are pushed onto the top
+of the stack is accomplished by swapping the contents of the file
+descriptor being pushed and the stack's current top layer file
+descriptor.
+
+The intent is that the pointer to the stack remain the stack's identity
+even if someone (perhaps covertly) has pushed other layers. Some subtle
+ramifications:
+
+- The ownership of the storage pointed to by the caller's layer
+ argument is relinquished to the runtime. Accessing the object via the
+ pointer is not permitted while the runtime has ownership. The correct
+ mechanism to access the object is to get a pointer to it by calling
+ :ref:`PR_GetIdentitiesLayer`.
+
+- The contents of the caller's object are swapped into another
+ container, including the reference to the object's destructor. If the
+ original container was allocated using a different mechanism than
+ used by the runtime, the default calling of the layer's destructor by
+ the runtime will fail :ref:`PR_CreateIOLayerStub` is provided to
+ allocate layer objects and template implementations). The destructor
+ will be called on all layers when the stack is closed (see
+ :ref:`PR_Close`). If the containers are allocated by some method other
+ than :ref:`PR_CreateIOLayerStub`, it may be required that the stack have
+ the layers popped off (in reverse order that they were pushed) before
+ calling :ref:`PR_Close`.

+------
+
+.. code::
+
+ #include <prio.h>
+
+ PRDirEntry* PR_ReadDir(
+ PRDir *dir,
+ PRDirFlags flags);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``dir``
+ A pointer to a :ref:`PRDir` object that designates an open directory.
+``flags``
+ Specifies which directory entries, if any, to skip. Values can
+ include the following:
+
+ - :ref:`PR_SKIP_NONE`. Do not skip any files.
+ - :ref:`PR_SKIP_DOT`. Skip the directory entry "." representing the
+ current directory.
+ - :ref:`PR_SKIP_DOT_DOT`. Skip the directory entry ".." representing
+ the parent directory.
+ - :ref:`PR_SKIP_BOTH`. Skip both "." and ".."
+ - :ref:`PR_SKIP_HIDDEN`. Skip hidden files. On Windows platforms and
+ the Mac OS, this value identifies files with the "hidden"
+ attribute set. On Unix platform, this value identifies files whose
+ names begin with a period (".").
+
+
+Returns
+~~~~~~~
+
+- A pointer to the next entry in the directory.
+- If the end of the directory is reached or an error occurs, ``NULL``.
+ The reason can be retrieved via :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+:ref:`PR_ReadDir` returns a pointer to a directory entry structure:
+
+.. code::
+
+ struct PRDirEntry {
+ const char *name;
+ };
+
+ typedef struct PRDirEntry PRDirEntry;
+
+The structure has the following field:
+
+``name``
+ Name of entry, relative to directory name.
+
+The ``flags`` parameter is an enum of type ``PRDirFlags``:
+
+.. code::
+
+ typedef enum PRDirFlags {
+ PR_SKIP_NONE = 0x0,
+ PR_SKIP_DOT = 0x1,
+ PR_SKIP_DOT_DOT = 0x2,
+ PR_SKIP_BOTH = 0x3,
+ PR_SKIP_HIDDEN = 0x4
+ } PRDirFlags;
+
+The memory associated with the returned PRDirEntry structure is managed
+by NSPR. The caller must not free the ``PRDirEntry`` structure.
+Moreover, the ``PRDirEntry`` structure returned by each :ref:`PR_ReadDir`
+call is valid only until the next :ref:`PR_ReadDir` or :ref:`PR_CloseDir` call
+on the same :ref:`PRDir` object.
+
+If the end of the directory is reached, :ref:`PR_ReadDir` returns ``NULL``,
+and :ref:`PR_GetError` returns ``PR_NO_MORE_FILES_ERROR``.

+PR_SetConcurrency
+=================
+
+Creates extra virtual processor threads. Generally used with MP systems.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prinit.h>
+
+ void PR_SetConcurrency(PRUintn numCPUs);
+
+
+Parameter
+~~~~~~~~~
+
+:ref:`PR_SetConcurrency` has one parameter:
+
+``numCPUs``
+ The number of extra virtual processor threads to be created.
+
+
+Description
+-----------
+
+Setting concurrency controls the number of virtual processors that NSPR
+uses to implement its ``M x N`` threading model. The ``M x N`` model is
+not available on all host systems. On those where it is not available,
+:ref:`PR_SetConcurrency` is ignored.
+
+Virtual processors are actually\ *global* threads, each of which is
+designed to support an arbitrary number of\ *local* threads. Since
+global threads are scheduled by the host operating system, this model is
+particularly applicable to multiprocessor architectures, where true
+parallelism is possible. However, it may also prove advantageous on
+uniprocessor systems to reduce the impact of having a locally scheduled
+thread calling incidental blocking functions. In such cases, all the
+threads being supported by the virtual processor will block, but those
+assigned to another virtual processor will be unaffected.

+~~~~~~~~~~
+
+The function has these parameters:

+ The NSPR (platform-independent) translation of the error.
+
+``oserr``
+ The platform-specific error. If there is no appropriate OS error
+ number, a zero may be supplied.

+
+ void PR_SetErrorText(PRIntn textLength, const char *text)

+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+``textLength``
+ The length of the text in the ``text``. May be ``NULL``. If not
+ ``NULL``, and if ``text`` is zero, the string is assumed to be a
+ null-terminated C string. Otherwise the text is assumed to be the
+ length specified and to possibly include ``NULL`` characters (as
+ might occur in a multilingual string).
+
+``text``
+ The text to associate with the error.
+
+
+Description
+-----------
+
+The text is copied into the thread structure and remains there until the
+next call to :ref:`PR_SetError`. If there is error text already present in
+the thread, the previous value is first deleted. The new value is copied
+into storage allocated and owned by NSPR and remains there until the
+next call to :ref:`PR_SetError` or another call to :ref:`PR_SetErrorText`.
+
+NSPR makes no use of this function. Clients may use it for their own
+purposes.

+ An index into the per-thread private data table.

+~~~~~~~
+
+The function returns one of the following values:

+
+
+Description
+-----------
+
+If the thread already has non-``NULL`` private data associated with it,
+and if the destructor function for the index is known (not ``NULL``),
+NSPR calls the destructor function associated with the index before
+setting the new data value. The pointer at the index is swapped with
+``NULL``. If the swapped out value is not ``NULL``, the destructor
+function is called. On return, the private data associated with the
+index is reassigned the new private data's value, even if it is
+``NULL``. The runtime provides no protection for the private data. The
+destructor is called with the runtime holding no locks. Synchronization
+is the client's responsibility.
+
+The only way to eliminate thread private data at an index prior to the
+thread's termination is to call :ref:`PR_SetThreadPrivate` with a ``NULL``
+argument. This causes the index's destructor function to be called, and
+afterwards assigns a ``NULL`` in the table. A client must not delete the
+referent object of a non-``NULL`` private data without first eliminating
+it from the table.

+PR_Wait
+=======
+

+

+Syntax
+------
+
+.. code::
+
+ #include <prmon.h>
+
+ PRStatus PR_Wait(
+ PRMonitor *mon,
+ PRIntervalTime ticks);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameter:
+
+``mon``
+ A reference to an existing structure of type :ref:`PRMonitor`. The
+ monitor object referenced must be one for which the calling thread
+ currently holds the lock.
+``ticks``
+ The amount of time (in :ref:`PRIntervalTime` units) that the thread is
+ willing to wait for an explicit notification before being
+ rescheduled.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+ - :ref:`PR_SUCCESS`` means the thread is being resumed from the ``PR_Wait`
+ call either because it was explicitly notified or because the time
+ specified by the parameter ``ticks`` has expired.
+ - :ref:`PR_FAILURE` means ``PR_Wait`` encountered a system error (such as
+ an invalid monitor reference) or the thread was interrupted by
+ another thread.
+
+
+Description
+-----------
+
+A call to :ref:`PR_Wait` causes the thread to release the monitor's lock,
+just as if it had called :ref:`PR_ExitMonitor` as many times as it had
+called :ref:`PR_EnterMonitor`. This has the effect of making the monitor
+available to other threads. When the wait is over, the thread regains
+control of the monitor's lock with the same entry count it had before
+the wait began.
+
+A thread waiting on the monitor resumes when the monitor is notified or
+when the timeout specified by the ``ticks`` parameter elapses. The
+resumption from the wait is merely a hint that a change of state has
+occurred. It is the responsibility of the programmer to evaluate the
+data and act accordingly. This is usually done by evaluating a Boolean
+expression involving the monitored data. While the Boolean expression is
+false, the thread should wait. The thread should act on the data only
+when the expression is true. The boolean expression must be evaluated
+while in the monitor and within a loop.
+
+In pseudo-code, the sequence is as follows:
+
+| ``PR_EnterMonitor(&ml);``
+| ``while (!expression) wait;``
+| ``... act on the state change ...``
+| ``PR_ExitMonitor(&ml);``
+
+A thread can be resumed from a wait for a variety of reasons. The most
+obvious is that it was notified by another thread. If the value of
+timeout is not ``PR_INTERVAL_NO_TIMEOUT``, :ref:`PR_Wait` resumes execution
+after the specified interval has expired. If a timeout value is used,
+the Boolean expression must include elapsed time as part of the
+monitored data.
+
+Resuming from the wait is merely an opportunity to evaluate the
+expression, not an assertion that the expression is true.

+
+
+Parameters
+~~~~~~~~~~
+
+:ref:`PR_WaitCondVar` has the following parameters:
+
+``cvar``
+ The condition variable on which to wait.
+``timeout``
+ The value ``PR_INTERVAL_NO_TIMEOUT`` requires that a condition be
+ notified (or the thread interrupted) before it will resume from the
+ wait. The value ``PR_INTERVAL_NO_WAIT`` causes the thread to release
+ the lock, possibly causing a rescheduling within the runtime, then
+ immediately attempt to reacquire the lock and resume.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+- If successful, ``PR_SUCCESS``.
+- If unsuccessful (for example, if the caller has not locked the lock
+ associated with the condition variable or the thread was interrupted
+ with :ref:`PR_Interrupt`), ``PR_FAILURE``. The details can be determined
+ with :ref:`PR_GetError`.
+
+
+Description
+-----------
+
+Before the call to :ref:`PR_WaitCondVar`, the lock associated with the
+condition variable must be held by the calling thread. After a call to
+:ref:`PR_WaitCondVar`, the lock is released and the thread is blocked in a
+"waiting on condition" state until another thread notifies the condition
+or a caller-specified amount of time expires.
+
+When the condition variable is notified, a thread waiting on that
+condition moves from the "waiting on condition" state to the "ready"
+state. When scheduled, the thread attempts to reacquire the lock that it
+held when :ref:`PR_WaitCondVar` was called.
+
+Any value other than ``PR_INTERVAL_NO_TIMEOUT`` or
+``PR_INTERVAL_NO_WAIT`` for the timeout parameter will cause the thread
+to be rescheduled due to either explicit notification or the expiration
+of the specified interval. The latter must be determined by treating
+time as one part of the monitored data being protected by the lock and
+tested explicitly for an expired interval. To detect the expiration of
+the specified interval, call :ref:`PR_IntervalNow` before and after the
+call to :ref:`PR_WaitCondVar` and compare the elapsed time with the
+specified interval.

+ - :ref:`PR_TOP_IO_LAYER`, the identity of the top of the stack
+ - :ref:`PR_NSPR_IO_LAYER`, the identity used by NSPR proper
+
+Layers are created by :ref:`PR_GetUniqueIdentity`. A string may be
+associated with a layer when the layer is created. The string is copied
+by the runtime, and :ref:`PR_GetNameForIdentity` returns a reference to
+that copy. There is no way to delete a layer's identity after the layer

+-----------
+
+The opaque structure :ref:`PRDir` represents an open directory in the file
+system. The function :ref:`PR_OpenDir` opens a specified directory and
+returns a pointer to a :ref:`PRDir` structure, which can be passed to
+:ref:`PR_ReadDir` repeatedly to obtain successive entries (files or
+subdirectories in the open directory). To close the directory, pass the
+:ref:`PRDir` pointer to :ref:`PR_CloseDir`.

+Description
+-----------
+
+The service NSPR offers in this area is the ability to associate a
+thread-specific condition with an error number. The error number
+namespace is not well managed. NSPR assumes error numbers starting at
+-6000 (decimal) and progressing towards zero. At present less than 100
+error codes have been defined. If NSPR's error handling is adopted by
+calling clients, then some sort of partitioning of the namespace will
+have to be employed. NSPR does not attempt to address this issue.
+
+For NSPR errors, see `Error Codes <NSPR_Error_Handling#Error_Code>`__.

+PRExplodedTime
+==============
+
+A clock/calendar representation of times.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prtime.h>
+
+ typedef struct PRExplodedTime {
+ PRInt32 tm_usec;
+ PRInt32 tm_sec;
+ PRInt32 tm_min;
+ PRInt32 tm_hour;
+ PRInt32 tm_mday;
+ PRInt32 tm_month;
+ PRInt16 tm_year;
+ PRInt8 tm_wday;
+ PRInt16 tm_yday;
+ PRTimeParameters tm_params;
+ } PRExplodedTime;
+
+
+Description
+-----------
+
+The :ref:`PRExplodedTime` structure represents clock/calendar time.
+:ref:`PRExplodedTime` has the familiar time components: year, month, day of
+month, hour, minute, second. It also has a microsecond component, as
+well as the day of week and the day of year. In addition,
+:ref:`PRExplodedTime` includes a :ref:`PRTimeParameters` structure
+representing the local time zone information, so that the time point is
+non-ambiguously specified.
+
+The essential members of :ref:`PRExplodedTime` are:
+
+ - :ref:`tm_year`: absolute year, AD (by "absolute," we mean if the year is
+ 2000, this field's value is 2000).
+ - :ref:`tm_month`: number of months past tm_year. The range is [0, 11]. 0
+ is January and 11 is December.
+ - :ref:`tm_mday`: the day of month. The range is [1, 31]. Note that it
+ starts from 1 as opposed to 0.
+ - :ref:`tm_hour`: number of hours past tm_mday. The range is [0, 23].
+ - :ref:`tm_min`: number of minutes past tm_hour. The range is [0, 59].
+ - :ref:`tm_sec`: number of seconds past tm_min. The range is [0, 61]. The
+ values 60 and 61 are for accommodating up to two leap seconds.
+ - :ref:`tm_usec`: number of microseconds past tm_sec. The range is [0,
+ 999999].
+ - :ref:`tm_params`: a `PRTimeParameters` structure representing the
+ local time zone information.
+
+The nonessential members of :ref:`PRExplodedTime` are:
+
+ - :ref:`tm_wday`: day of week. The range is [0, 6]. 0 is Sunday, 1 is
+ Monday, and 6 is Saturday.
+ - :ref:`tm_yday`: day of year. The range is [0, 365]. 0 is the 1st of
+ January.
+
+On input to NSPR functions, only the essential members of
+:ref:`PRExplodedTime` must be specified. The two nonessential members (day
+of week and day of year) are ignored by NSPR functions as input. When an
+NSPR function returns a :ref:`PRExplodedTime` object or sets a
+:ref:`PRExplodedTime` object as output, all of the :ref:`PRExplodedTime`
+members are set, including the nonessential members. You can also use
+``PR_NormalizeTime()`` to calculate the values of the nonessential
+members.

+Description
+-----------
+
+The fields of this structure are significant only if you are

+PRHostEnt
+=========
+
+A structure that defines a list of network addresses. This structure is
+output from :ref:`PR_GetHostByName` and :ref:`PR_GetHostByAddr` and passed to
+:ref:`PR_EnumerateHostEnt`. Clients should avoid directly accessing any of
+the structure's fields.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prnetdb.h>
+
+ typedef struct PRHostEnt {
+ char *h_name;
+ char **h_aliases;
+ #if defined(_WIN32)
+ PRInt16 h_addrtype;

+ #else
+ PRInt32 h_addrtype;
+ PRInt32 h_length;
+ #endif
+ char **h_addr_list;
+ } PRHostEnt;
+
+
+Fields
+~~~~~~
+
+The structure has the following fields:
+
+``h_name``
+ Pointer to the official name of host.
+``h_aliases``
+ Pointer to a pointer to list of aliases. The list is terminated with
+ a ``NULL`` entry.
+``h_addrtype``
+ Host address type. For valid NSPR usage, this field must have a value
+ indicating either an IPv4 or an IPv6 address.
+``h_length``
+ Length of internal representation of the address in bytes. All of the
+ addresses in the list are of the same type and therefore of the same
+ length.
+``h_addr_list``
+ Pointer to a pointer to a list of addresses from name server (in
+ network byte order). The list is terminated with a ``NULL`` entry.
+
+
+Description
+-----------
+
+This structure is used by many of the network address functions. All
+addresses are passed in host order and returned in network order
+(suitable for use in system calls).
+
+Use the network address functions to manipulate the :ref:`PRHostEnt`
+structure. To make the transition to IP version 6 easier, it's best to
+treat :ref:`PRHostEnt` as an opaque structure.
+
+Note
+----
+
+``WINSOCK.H`` defines ``h_addrtype`` and ``h_length`` as a 16-bit field,
+whereas other platforms treat it as a 32-bit field. The ``#ifdef`` in
+the structure allows direct assignment of the :ref:`PRHostEnt` structure.

+PRIntervalTime
+==============
+
+A platform-dependent type that represents a monotonically increasing
+integer--the NSPR runtime clock.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <prinrval.h>
+
+ typedef PRUint32 PRIntervalTime;
+
+ #define PR_INTERVAL_MIN 1000UL
+ #define PR_INTERVAL_MAX 100000UL
+
+ #define PR_INTERVAL_NO_WAIT 0UL
+ #define PR_INTERVAL_NO_TIMEOUT 0xffffffffUL
+
+
+Description
+-----------
+
+The units of :ref:`PRIntervalTime` are platform-dependent. They are chosen
+to be appropriate for the host OS, yet provide sufficient resolution and
+period to be useful to clients.
+
+The increasing interval value represented by :ref:`PRIntervalTime` wraps.
+It should therefore never be used for intervals greater than
+approximately 6 hours. Interval times are accurate regardless of host
+processing requirements and are very cheap to acquire.
+
+The constants ``PR_INTERVAL_MIN`` and ``PR_INTERVAL_MAX`` define a range
+in ticks per second. These constants bound both the period and the
+resolution of a :ref:`PRIntervalTime` object.
+
+The reserved constants ``PR_INTERVAL_NO_WAIT`` and
+``PR_INTERVAL_NO_TIMEOUT`` have special meaning for NSPR. They indicate
+that the process should wait no time (return immediately) or wait
+forever (never time out), respectively.
+
+.. _Important_Note:
+
+Important Note
+~~~~~~~~~~~~~~
+
+The counters used for interval times are allowed to overflow. Since the
+sampling of the counter used to define an arbitrary epoch may have any
+32-bit value, some care must be taken in the use of interval times. The
+proper coding style to test the expiration of an interval is as follows:
+
+.. code::
+
+ if ((PRIntervalTime)(now - epoch) > interval)
+ <... interval has expired ...>
+
+As long as the interval and the elapsed time (now - epoch) do not exceed
+half the namespace allowed by a :ref:`PRIntervalTime` (2\ :sup:`31`-1), the
+expression shown above provides the expected result even if the signs of
+now and epoch differ.
+
+The resolution of a :ref:`PRIntervalTime` object is defined by the API.
+NSPR guarantees that there will be at least 1000 ticks per second and
+not more than 100000. At the maximum resolution of 10000 ticks per
+second, each tick represents 1/100000 of a second. At that rate, a
+32-bit register will overflow in approximately 28 hours, making the
+maximum useful interval approximately 6 hours. Waiting on events more
+than half a day in the future must therefore be based on a calendar
+time.

+
+Description
+-----------
+
+You don't need to know the type declaration for each function listed in
+the method table unless you are implementing a layer. For information
+about each function, see the corresponding function description in this
+document. For example, the ``write`` method in :ref:`PRIOMethods`
+implements the :ref:`PR_Write` function. For type definition details, see
+``prio.h``.
+
+The I/O methods table provides procedural access to the functions of the
+file descriptor. It is the responsibility of a layer implementor to
+provide suitable functions at every entry point (that is, for every
+function in the I/O methods table). If a layer provides no
+functionality, it should call the next lower (higher) function of the
+same name (for example, the "close" method would return
+``fd->lower->method->close(fd->lower)``).
+
+Not all functions in the methods table are implemented for all types of
+files. For example, the seek method is implemented for normal files but
+not for sockets. In cases where this partial implementation occurs, the
+function returns an error indication with an error code of
+``PR_INVALID_METHOD_ERROR``.

+
+PRIPv6Addr represents a 128-bit IPv6 address. It is equivalent to struct
+``in6_addr`` in the Berkeley socket interface. :ref:`PRIPv6Addr` is always
+manipulated as a byte array. Unlike the IPv4 address (a 4-byte unsigned

+PRLinger
+========
+
+Structure used with the ``PR_SockOpt_Linger`` socket option to specify

+ } PRLinger;
+
+
+Fields
+~~~~~~
+
+The structure has the following fields:
+
+``polarity``
+ Polarity of the option's setting: ``PR_FALSE`` means the option is
+ off, in which case the value of ``linger`` is ignored. ``PR_TRUE``
+ means the option is on, and the value of ``linger`` will be used to
+ determine how long :ref:`PR_Close` waits before returning.
+``linger``
+ Time (in :ref:`PRIntervalTime` units) to linger before closing if any
+ data remain in the socket send buffer.
+
+
+Description
+~~~~~~~~~~~
+
+By default, :ref:`PR_Close` returns immediately, but if there are any data
+remaining in the socket send buffer, the system attempts to deliver the
+data to the peer. The ``PR_SockOpt_Linger`` socket option, with a value
+represented by a structure of type :ref:`PRLinger`, makes it possible to
+change this default as follows:
+
+- If ``polarity`` is set to ``PR_FALSE``, :ref:`PR_Close` returns
+ immediately, but if there are any data remaining in the socket send
+ buffer, the runtime attempts to deliver the data to the peer.
+- If ``polarity`` is set to ``PR_TRUE`` and ``linger`` is set to 0
+ (``PR_INTERVAL_NO_WAIT``), the runtime aborts the connection when it
+ is closed and discards any data remaining in the socket send buffer.
+- If ``polarity`` is set to ``PR_TRUE`` and ``linger`` is nonzero, the
+ runtime *lingers* when the socket is closed. That is, if any data
+ remains in the socket send buffer, :ref:`PR_Close` blocks until either
+ all the data is sent and acknowledged by the peer or the interval
+ specified by ``linger`` expires.

+``flowinfo``
+ Routing information.
+
+
+Description
+-----------
+
+The union :ref:`PRNetAddr` represents a network address. NSPR supports only
+the Internet address family. By default, NSPR is built to support only
+IPv4, but it's possible to build the NSPR library to support both IPv4
+and IPv6. Therefore, the ``family`` field can be ``PR_AF_INET`` only for
+default NSPR, and can also be ``PR_AF_INET6`` if the binary supports
+``IPv6``.
+
+:ref:`PRNetAddr` is binary-compatible with the socket address structures in
+the familiar Berkeley socket interface, although this fact should not be
+relied upon. The raw member of the union is equivalent to
+``struct sockaddr``, the ``inet`` member is equivalent to
+``struct sockaddr_in``, and if the binary is built with ``IPv6``
+support, the ``ipv6`` member is equivalent to ``struct sockaddr_in6``.
+(Note that :ref:`PRNetAddr` does not have the ``length`` field that is
+present in ``struct sockaddr_in`` on some Unix platforms.)
+
+The macros ``PR_AF_INET``, ``PR_AF_INET6``, ``PR_INADDR_ANY``,
+``PR_INADDR_LOOPBACK`` are defined if ``prio.h`` is included.
+``PR_INADDR_ANY`` and ``PR_INADDR_LOOPBACK`` are special ``IPv4``
+addresses in host byte order, so they must be converted to network byte
+order before being assigned to the ``inet.ip`` field.

+necessary.
+
+Implicit initialization assumes that the initiator is the primordial
+thread and that the thread is a user thread of normal priority.

+Process Management And Interprocess Communication
+=================================================
+
+This chapter describes the NSPR routines that deal with processes. A
+process is an instance of a program. NSPR provides routines to create a
+new process and to wait for the termination of another process.
+
+NSPR does not provide an equivalent of the Unix ``fork()``. The
+newly-created process executes its program from the beginning. A new
+process can inherit specified file descriptors from its parent, and the
+parent can redirect the standard I/O streams of the child process to
+specified file descriptors.
+
+Note that the functions described in this chapter are not available for
+MacOS or Win16 operating systems.

+A static link table entry can be created by a client of the runtime so

+The basic function on a dynamic library is to acquire a pointer to a
+function that the library exports. If, during initialization, such

+
+
+Description
+-----------
+
+In general, an NSPR thread of higher priority has a statistically better
+chance of running relative to threads of lower priority. However,
+because of the multiple strategies NSPR uses to implement threading on
+various host platforms, NSPR priorities are not precisely defined. At
+best they are intended to specify a preference in the amount of CPU time
+that a higher-priority thread might expect relative to a lower-priority
+thread. This preference is still subject to resource availability and
+must not be used in place of proper synchronization.

+``PR_GLOBAL_BOUND_THREAD``
+ A global bound (kernel) thread, scheduled by the host OS
+
+
+Description
+-----------
+
+An enumerator of type :ref:`PRThreadScope` specifies how a thread is
+scheduled: either locally by NSPR within the process (a local thread) or
+globally by the host (a global thread).
+
+Global threads are scheduled by the host OS and compete with all other
+threads on the host OS for resources. They are subject to fairly
+sophisticated scheduling techniques.
+
+Local threads are scheduled by NSPR within the process. The process is
+assumed to be globally scheduled, but NSPR can manipulate local threads
+without system intervention. In most cases, this leads to a significant
+performance benefit.
+
+However, on systems that require NSPR to make a distinction between
+global and local threads, global threads are invariably required to do
+any form of I/O. If a thread is likely to do a lot of I/O, making it a
+global thread early is probably warranted.
+
+On systems that don't make a distinction between local and global
+threads, NSPR silently ignores the scheduling request. To find the scope
+of the thread, call :ref:`PR_GetThreadScope`.

+``PR_UNJOINABLE_THREAD``
+ Thread termination happens implicitly when the thread returns from
+ the root function. The time of release of the resources assigned to
+ the thread cannot be determined in advance. Threads created with a
+ ``PR_UNJOINABLE_THREAD`` state cannot be used as arguments to
+ :ref:`PR_JoinThread`.
+``PR_JOINABLE_THREAD``
+ Joinable thread references remain valid after they have returned from
+ their root function until :ref:`PR_JoinThread` is called. This approach
+ facilitates management of the process' critical resources.
+
+
+Description
+-----------
+
+A thread is a critical resource and must be managed.
+
+The lifetime of a thread extends from the time it is created to the time
+it returns from its root function. What happens when it returns from its
+root function depends on the thread state passed to :ref:`PR_CreateThread`
+when the thread was created.
+
+If a thread is created as a joinable thread, it continues to exist after
+returning from its root function until another thread joins it. The join
+process permits strict synchronization of thread termination and
+therefore promotes effective resource management.
+
+If a thread is created as an unjoinable (also called detached) thread,
+it terminates and cleans up after itself after returning from its root
+function. This results in some ambiguity after the thread's root
+function has returned and before the thread has finished terminating
+itself.

+PRTimeParameters
+================
+
+A representation of time zone information.

+
+ typedef struct PRTimeParameters {
+ PRInt32 tp_gmt_offset;
+ PRInt32 tp_dst_offset;
+ } PRTimeParameters;
+
+
+Description
+-----------
+
+Each geographic location has a standard time zone, and if Daylight
+Saving Time (DST) is practiced, a daylight time zone. The
+:ref:`PRTimeParameters` structure represents the local time zone
+information in terms of the offset (in seconds) from GMT. The overall
+offset is broken into two components:
+
+``tp_gmt_offset``
+ The offset of the local standard time from GMT.
+
+``tp_dst_offset``
+ If daylight savings time (DST) is in effect, the DST adjustment from
+ the local standard time. This is most commonly 1 hour, but may also
+ be 30 minutes or some other amount. If DST is not in effect, the
+ tp_dst_offset component is 0.
+
+For example, the US Pacific Time Zone has both a standard time zone
+(Pacific Standard Time, or PST) and a daylight time zone (Pacific
+Daylight Time, or PDT).
+
+- In PST, the local time is 8 hours behind GMT, so ``tp_gmt_offset`` is
+ -28800 seconds. ``tp_dst_offset`` is 0, indicating that daylight
+ saving time is not in effect.
+
+- In PDT, the clock is turned forward by one hour, so the local time is
+ 7 hours behind GMT. This is broken down as -8 + 1 hours, so
+ ``tp_gmt_offset`` is -28800 seconds, and ``tp_dst_offset`` is 3600
+ seconds.
+
+A second example is Japan, which is 9 hours ahead of GMT. Japan does not
+use daylight saving time, so the only time zone is Japan Standard Time
+(JST). In JST ``tp_gmt_offset`` is 32400 seconds, and ``tp_dst_offset``
+is 0.

+NSPR provides an execution environment that promotes the use of
+lightweight threads. Each thread is an execution entity that is
+scheduled independently from other threads in the same process. This
+chapter describes the basic NSPR threading API.
+
+- `Threading Types and Constants <#Threading_Types_and_Constants>`__
+- `Threading Functions <#Threading_Functions>`__
+
+A thread has a limited number of resources that it truly owns. These
+resources include a stack and the CPU registers (including PC). To an
+NSPR client, a thread is represented by a pointer to an opaque structure
+of type :ref:`PRThread`. A thread is created by an explicit client request
+and remains a valid, independent execution entity until it returns from
+its root function or the process abnormally terminates. Threads are
+critical resources and therefore require some management. To synchronize
+the termination of a thread, you can **join** it with another thread
+(see :ref:`PR_JoinThread`). Joining a thread provides definitive proof that
+the target thread has terminated and has finished with both the
+resources to which the thread has access and the resources of the thread
+itself.
+
+For an overview of the NSPR threading model and sample code that
+illustrates its use, see `Introduction to
+NSPR <Introduction_to_NSPR>`__.

+Running NSPR tests
+==================
+
+NSPR has a test suite in the ``mozilla/nsprpub/pr/tests`` directory.
+
+By default, we don't build the test programs. Running ``gmake`` in the
+top-level directory (``mozilla/nsprpub``) only builds the NSPR
+libraries. To build the test programs, you need to change directory to
+``mozilla/nsprpub/pr/tests`` and run ``gmake``. Refer to :ref:`NSPR build
+instructions` for details.
+
+To run the test suite, run the shell script
+``mozilla/nsprpub/pr/tests/runtests.sh`` in the directory where the test
+program binaries reside, for example,
+
+.. code::
+
+ cvs -q co -r NSPR_4_6_6_RTM mozilla/nsprpub
+ mkdir linux.debug
+ cd linux.debug
+ ../mozilla/nsprpub/configure
+ gmake
+ cd pr/tests
+ gmake
+ ../../../mozilla/nsprpub/pr/tests/runtests.sh
+
+The output of the test suite looks like this:
+
+.. code::

+How to determine if the test suite passed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If all the tests reported **Passed** as the results, the test suite
+passed.
+
+What if some of the tests crashed or reported **FAILED** as the results?
+It doesn't necessarily mean the test suite failed because some of the
+test programs are known to fail. Until the test failures are fixed, you
+should run NSPR tests against **a known good version of NSPR on the same
+platform**, and save the test results as the benchmark. Then you can
+detect regressions of the new version by comparing its test results with
+the benchmark.
+
+.. _Known_issues:
+
+Known issues
+~~~~~~~~~~~~
+
+Other issues with the NSPR test suite are:
+
+#. Some of the test programs test the accuracy of the timeout of NSPR
+ functions. Since none of our operating systems is a real-time OS,
+ such test programs may fail when the test machine is heavily loaded.
+#. Some tests, such as ``pipepong`` and ``sockpong``, should not be run
+ directly. They will be invoked by their companion test programs
+ (e.g., ``pipeping`` and ``sockping``). This is not an issue if you
+ run ``runtests.sh`` because ``runtests.sh`` knows not to run such
+ test programs directly.

+This technical memo is a cautionary note on using NetScape Portable
+Runtime's (NSPR) IO timeout and interrupt on Windows NT 3.51 and 4.0.
+Due to a limitation of the present implementation of NSPR IO on NT,
+programs must follow the following guideline:
+
+If a thread calls an NSPR IO function on a file descriptor and the IO
+function fails with <tt>PR_IO_TIMEOUT_ERROR</tt> or
+<tt>PR_PENDING_INTERRUPT_ERROR</tt>, the file descriptor must be closed
+before the thread exits.
+
+In this memo we explain the problem this guideline is trying to work
+around and discuss its limitations.
+
+.. _NSPR_IO_on_NT:
+
+NSPR IO on NT
+-------------
+
+The IO model of NSPR 2.0 is synchronous and blocking. A thread calling
+an IO function is blocked until the IO operation finishes, either due to
+a successful IO completion or an error. If the IO operation cannot
+complete before the specified timeout, the IO function returns with
+<tt>PR_IO_TIMEOUT_ERROR</tt>. If the thread gets interrupted by another
+thread's <tt>PR_Interrupt()</tt> call, the IO function returns with
+<tt>PR_PENDING_INTERRUPT_ERROR</tt>.
+
+On Windows NT, NSPR IO is implemented using NT's *overlapped* (also
+called *asynchronous*) *IO*. When a thread calls an IO function, the
+thread issues an overlapped IO request using the overlapped buffer in
+its <tt>PRThread</tt> structure. Then the thread is put to sleep. In the
+meantime, there are dedicated internal threads (called the *idle
+threads*) monitoring the IO completion port for completed IO requests.
+If a completed IO request appears at the IO completion port, an idle
+thread fetches it and wakes up the thread that issued the IO request
+earlier. This is the normal way the thread is awakened.
+
+.. _IO_Timeout_and_Interrupt:
+
+IO Timeout and Interrupt
+------------------------
+
+However, NSPR may wake up the thread in two other situations:
+
+- if the overlapped IO request is not completed before the specified
+ timeout. (Note that we can't specify timeout on overlapped IO
+ requests, so the timeouts are all handled at the NSPR level.) In this
+ case, the error is <tt>PR_IO_TIMEOUT_ERROR</tt>.
+- if the thread gets interrupted by another thread's
+ <tt>PR_Interrupt()</tt> call. In this case, the error is
+ <tt>PR_PENDING_INTERRUPT_ERROR</tt>.
+
+These two errors are generated by the NSPR layer, so the OS is oblivious
+of what is going on and the overlapped IO request is still in progress.
+The OS still has a pointer to the overlapped buffer in the thread's
+<tt>PRThread</tt> structure. If the thread subsequently exists and its
+<tt>PRThread</tt> structure gets deleted, the pointer to the overlapped
+buffer will be pointing to freed memory. This is problematic.
+
+.. _Canceling_Overlapped_IO_by_Closing_the_File_Descriptor:
+
+Canceling Overlapped IO by Closing the File Descriptor
+------------------------------------------------------
+
+Therefore, we need to cancel the outstanding overlapped IO request
+before the thread exits. NT's <tt>CancelIo()</tt> function would be
+ideal for this purpose. Unfortunately, <tt>CancelIo()</tt> is not
+available on NT 3.51. So we can't go this route as long as we are
+supporting NT 3.51. The only reliable way to cancel outstanding
+overlapped IO request that works on both NT 3.51 and 4.0 is to close the
+file descriptor, hence the rule of thumb stated at the beginning of this
+memo.
+
+.. _Limitations:
+
+Limitations
+-----------
+
+This seemingly harsh way to force the completion of outstanding
+overlapped IO request has the following limitations:
+
+- It is difficult for threads to shared a file descriptor. For example,
+ suppose thread A and thread B call <tt>PR_Accept()</tt> on the same
+ socket, and they time out at the same time. Following the rule of
+ thumb, both threads would close the socket. The first
+ <tt>PR_Close()</tt> would succeed, but the second <tt>PR_Close()</tt>
+ would be freeing freed memory. A solution that may work is to use a
+ lock to ensure only one thread can be using that socket at all times.
+- Once there is a timeout or interrupt error, the file descriptor is no
+ longer usable. Suppose the file descriptor is intended to be used for
+ the life time of the process, for example, the logging file, this is
+ really not acceptable. A possible solution is to add a
+ <tt>PR_DisableInterrupt()</tt> function to turn off interrupts when
+ accessing such file descriptors.
+
+..
+
+ *A related known bug is that timeout and interrupt don't work for
+ <tt>PR_Connect()</tt> on NT. This bug is due to a different
+ limitation in our NT implementation.*
+
+.. _Conclusions:
+
+Conclusions
+-----------
+
+As long as we need to support NT 3.51, we need to program under the
+guideline that after an IO timeout or interrupt error, the thread must
+make sure the file descriptor is closed before it exits. Programs should
+also take care in sharing file descriptors and using IO timeout or
+interrupt on files that need to stay open throughout the process.
+
+When we stop supporting NT 3.51, we can look into using NT 4's
+<tt>CancelIo()</tt> function to cancel outstanding overlapped IO
+requests when we get IO timeout or interrupt errors. If
+<tt>CancelIo()</tt> really works as advertised, that should
+fundamentally solve this problem.
+
+If these limitations with IO timeout and interrupt are not acceptable to
+the needs of your programs, you can consider using the Win95 version of
+NSPR. The Win95 version runs without trouble on NT, but you would lose
+the better performance provided by NT fibers and asynchronous IO.
