+/* The pthreads standard does not specify an invalid value for the

+ * invalid identifier. These macros are not portable and may be
+ * more of a problem as we adapt to more pthreads implementations.
+ * They are only used in the PRMonitor functions. Do not use them
+ * in new code.
+ *
+ * Unfortunately some of our clients depend on certain properties
+ * of our PRMonitor implementation, preventing us from replacing
+ * it by a portable implementation.
+ * - High-performance servers like the fact that PR_EnterMonitor
+ * only calls PR_Lock and PR_ExitMonitor only calls PR_Unlock.
+ * (A portable implementation would use a PRLock and a PRCondVar
+ * to implement the recursive lock in a monitor and call both
+ * PR_Lock and PR_Unlock in PR_EnterMonitor and PR_ExitMonitor.)
+ * Unfortunately this forces us to read the monitor owner field
+ * without holding a lock.
+ * - One way to make it safe to read the monitor owner field
+ * without holding a lock is to make that field a PRThread*
+ * (one should be able to read a pointer with a single machine
+ * instruction). However, PR_GetCurrentThread calls calloc if
+ * it is called by a thread that was not created by NSPR. The
+ * malloc tracing tools in the Mozilla client use PRMonitor for
+ * locking in their malloc, calloc, and free functions. If
+ * PR_EnterMonitor calls any of these functions, infinite
+ * recursion ensues.

+** Description: API to periodic alarms.
+**
+**
+** Alarms are defined to invoke some client specified function at
+** a time in the future. The notification may be a one time event
+** or repeated at a fixed interval. The interval at which the next
+** notification takes place may be modified by the client code only
+** during the respective notification.
+**
+** The notification is delivered on a thread that is part of the
+** alarm context (PRAlarm). The thread will inherit the priority
+** of the Alarm creator.
+**
+** Any number of periodic alarms (PRAlarmID) may be created within
+** the context of a single alarm (PRAlarm). The notifications will be
+** scheduled as close to the desired time as possible.
+**
+** Repeating periodic notifies are expected to run at a fixed rate.
+** That rate is expressed as some number of notifies per period where
+** the period is much larger than a PRIntervalTime (see prinrval.h).

+** prcountr.h -- NSPR Instrumentation counters
+**
+** The NSPR Counter Feature provides a means to "count
+** something." Counters can be dynamically defined, incremented,
+** decremented, set, and deleted under application program
+** control.
+**
+** The Counter Feature is intended to be used as instrumentation,
+** not as operational data. If you need a counter for operational
+** data, use native integral types.
+**
+** Counters are 32bit unsigned intergers. On overflow, a counter
+** will wrap. No exception is recognized or reported.
+**
+** A counter can be dynamically created using a two level naming
+** convention. A "handle" is returned when the counter is
+** created. The counter can subsequently be addressed by its
+** handle. An API is provided to get an existing counter's handle
+** given the names with which it was originally created.
+** Similarly, a counter's name can be retrieved given its handle.
+**
+** The counter naming convention is a two-level hierarchy. The
+** QName is the higher level of the hierarchy; RName is the
+** lower level. RNames can be thought of as existing within a
+** QName. The same RName can exist within multiple QNames. QNames
+** are unique. The NSPR Counter is not a near-zero overhead
+** feature. Application designers should be aware of
+** serialization issues when using the Counter API. Creating a
+** counter locks a large asset, potentially causing a stall. This
+** suggest that applications should create counters at component
+** initialization, for example, and not create and destroy them
+** willy-nilly. ... You have been warned.
+**
+** Incrementing and Adding to counters uses atomic operations.
+** The performance of these operations will vary from platform
+** to platform. On platforms where atomic operations are not
+** supported the overhead may be substantial.
+**
+** When traversing the counter database with FindNext functions,
+** the instantaneous values of any given counter is that at the
+** moment of extraction. The state of the entire counter database
+** may not be viewed as atomic.
+**
+** The counter interface may be disabled (No-Op'd) at compile
+** time. When DEBUG is defined at compile time, the Counter
+** Feature is compiled into NSPR and applications invoking it.
+** When DEBUG is not defined, the counter macros compile to
+** nothing. To force the Counter Feature to be compiled into an
+** optimized build, define FORCE_NSPR_COUNTERS at compile time
+** for both NSPR and the application intending to use it.
+**
+** Application designers should use the macro form of the Counter
+** Feature methods to minimize performance impact in optimized
+** builds. The macros normally compile to nothing on optimized
+** builds.
+**
+** Application designers should be aware of the effects of
+** debug and optimized build differences when using result of the
+** Counter Feature macros in expressions.
+**
+** The Counter Feature is thread-safe and SMP safe.

+** PR_GetEnv() -- Retrieve value of environment variable
+**
+** Description:
+** PR_GetEnv() is modeled on Unix getenv().
+**
+**
+** Inputs:
+** var -- The name of the environment variable
+**
+** Returns:
+** The value of the environment variable 'var' or NULL if
+** the variable is undefined.
+**
+** Restrictions:
+** You'd think that a POSIX getenv(), putenv() would be
+** consistently implemented everywhere. Surprise! It is not. On
+** some platforms, a putenv() where the argument is of
+** the form "name" causes the named environment variable to
+** be un-set; that is: a subsequent getenv() returns NULL. On
+** other platforms, the putenv() fails, on others, it is a
+** no-op. Similarly, a putenv() where the argument is of the
+** form "name=" causes the named environment variable to be
+** un-set; a subsequent call to getenv() returns NULL. On
+** other platforms, a subsequent call to getenv() returns a
+** pointer to a null-string (a byte of zero).
+**
+** PR_GetEnv(), PR_SetEnv() provide a consistent behavior
+** across all supported platforms. There are, however, some
+** restrictions and some practices you must use to achieve
+** consistent results everywhere.
+**
+** When manipulating the environment there is no way to un-set
+** an environment variable across all platforms. We suggest
+** you interpret the return of a pointer to null-string to
+** mean the same as a return of NULL from PR_GetEnv().
+**
+** A call to PR_SetEnv() where the parameter is of the form
+** "name" will return PR_FAILURE; the environment remains
+** unchanged. A call to PR_SetEnv() where the parameter is
+** of the form "name=" may un-set the envrionment variable on
+** some platforms; on others it may set the value of the
+** environment variable to the null-string.
+**
+** For example, to test for NULL return or return of the
+** null-string from PR_GetEnv(), use the following code
+** fragment:
+**
+** char *val = PR_GetEnv("foo");
+** if ((NULL == val) || ('\0' == *val)) {
+** ... interpret this as un-set ...
+** }
+**
+** The caller must ensure that the string passed
+** to PR_SetEnv() is persistent. That is: The string should
+** not be on the stack, where it can be overwritten
+** on return from the function calling PR_SetEnv().
+** Similarly, the string passed to PR_SetEnv() must not be
+** overwritten by other actions of the process. ... Some
+** platforms use the string by reference rather than copying
+** it into the environment space. ... You have been warned!
+**
+** Use of platform-native functions that manipulate the
+** environment (getenv(), putenv(),
+** SetEnvironmentVariable(), etc.) must not be used with
+** NSPR's similar functions. The platform-native functions
+** may not be thread safe and/or may operate on different
+** conceptual environment space than that operated upon by
+** NSPR's functions or other environment manipulating
+** functions on the same platform. (!)

+** this avoids needing to allocate memory or take locks in the child

+** In case of memory allocation failure, or if the operating system
+** doesn't support reading the entire environment through the global
+** variable "environ" or similar, returns NULL instead.

+** Description: Localizable error code to string function.
+**
+**
+** NSPR provides a mechanism for converting an error code to a
+** descriptive string, in a caller-specified language.
+**
+** Error codes themselves are 32 bit (signed) integers. Typically,
+** the high order 24 bits are an identifier of which error table the
+** error code is from, and the low order 8 bits are a sequential error
+** number within the table. NSPR supports error tables whose first
+** error code is not a multiple of 256, such error code assignments
+** should be avoided when possible.
+**
+** Error table 0 is defined to match the UNIX system call error table
+** (sys_errlist); this allows errno values to be used directly in the
+** library. Other error table numbers are typically formed by
+** compacting together the first four characters of the error table
+** name. The mapping between characters in the name and numeric
+** values in the error code are defined in a system-independent
+** fashion, so that two systems that can pass integral values between
+** them can reliably pass error codes without loss of meaning; this
+** should work even if the character sets used are not the
+** same. (However, if this is to be done, error table 0 should be
+** avoided, since the local system call error tables may differ.)
+**
+** Libraries defining error codes need only provide a table mapping
+** error code numbers to names and default English descriptions,
+** calling a routine to install the table, making it ``known'' to NSPR
+** library. Once installed, a table may not be removed. Any error
+** code the library generates can be converted to the corresponding
+** error message. There is also a default format for error codes
+** accidentally returned before making the table known, which is of
+** the form "unknown code foo 32", where "foo" would be the name of
+** the table.
+**
+** Normally, the error code conversion routine only supports the
+** languages "i-default" and "en", returning the error-table-provided
+** English description for both languages. The application may
+** provide a localization plugin, allowing support for additional
+** languages.

+** 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 PR_POLL_READ flag. You can't
+** 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 PR_Poll call. Pollable events
+** are implemented using a pipe or a pair of TCP sockets
+** connected via the loopback address, therefore setting and
+** 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.
+**
+** A new pollable event is created by a PR_NewPollableEvent
+** call and is initially in the unset state.
+**
+** PR_WaitForPollableEvent blocks the calling thread until
+** the pollable event is set, and then it atomically unsets
+** the pollable event before it returns.
+**
+** To set a pollable event, call PR_SetPollableEvent.
+**
+** One can call PR_Poll with the PR_POLL_READ flag on a pollable
+** event. When the pollable event is set, PR_Poll returns with
+** the PR_POLL_READ flag set in the out_flags.
+**
+** To close a pollable event, call PR_DestroyPollableEvent
+** (not PR_Close).

+***** A Word about Model Dependent Function Naming Convention ***********
+*************************************************************************/
+
+/*
+NSPR 2.0 must implement its function across a range of platforms
+including: MAC, Windows/16, Windows/95, Windows/NT, and several
+variants of Unix. Each implementation shares common code as well
+as having platform dependent portions. This standard describes how
+the model dependent portions are to be implemented.
+
+In header file pr/include/primpl.h, each publicly declared
+platform dependent function is declared as:
+
+NSPR_API void _PR_MD_FUNCTION( long arg1, long arg2 );
+#define _PR_MD_FUNCTION _MD_FUNCTION
+
+In header file pr/include/md/<platform>/_<platform>.h,
+each #define'd macro is redefined as one of:
+
+#define _MD_FUNCTION <blanks>
+#define _MD_FUNCTION <expanded macro>
+#define _MD_FUNCTION <osFunction>
+#define _MD_FUNCTION <_MD_Function>
+
+Where:
+
+<blanks> is no definition at all. In this case, the function is not implemented
+and is never called for this platform.
+For example:
+#define _MD_INIT_CPUS()
+
+<expanded macro> is a C language macro expansion.
+For example:
+#define _MD_CLEAN_THREAD(_thread) \
+ PR_BEGIN_MACRO \
+ PR_DestroyCondVar(_thread->md.asyncIOCVar); \
+ PR_DestroyLock(_thread->md.asyncIOLock); \
+ PR_END_MACRO
+
+<osFunction> is some function implemented by the host operating system.
+For example:
+#define _MD_EXIT exit
+
+<_MD_function> is the name of a function implemented for this platform in
+pr/src/md/<platform>/<soruce>.c file.
+For example:
+#define _MD_GETFILEINFO _MD_GetFileInfo
+
+In <source>.c, the implementation is:
+PR_IMPLEMENT(PRInt32) _MD_GetFileInfo(const char *fn, PRFileInfo *info);

+** prlog.h -- Declare interfaces to NSPR's Logging service
+**
+** NSPR provides a logging service that is used by NSPR itself and is
+** available to client programs.
+**
+** To use the service from a client program, you should create a
+** PRLogModuleInfo structure by calling PR_NewLogModule(). After
+** creating the LogModule, you can write to the log using the PR_LOG()
+** macro.
+**
+** Initialization of the log service is handled by NSPR initialization.
+**
+** At execution time, you must enable the log service. To enable the
+** log service, set the environment variable: NSPR_LOG_MODULES
+** variable.
+**
+** NSPR_LOG_MODULES variable has the form:
+**
+** <moduleName>:<value>[, <moduleName>:<value>]*
+**
+** Where:
+** <moduleName> is the name passed to PR_NewLogModule().
+** <value> is a numeric constant, e.g. 5. This value is the maximum
+** value of a log event, enumerated by PRLogModuleLevel, that you want
+** written to the log.
+**
+** For example: to record all events of greater value than or equal to
+** PR_LOG_ERROR for a LogModule names "gizmo", say:
+**
+** set NSPR_LOG_MODULES=gizmo:2
+**
+** Note that you must specify the numeric value of PR_LOG_ERROR.
+**
+** Special LogModule names are provided for controlling NSPR's log
+** service at execution time. These controls should be set in the
+** NSPR_LOG_MODULES environment variable at execution time to affect
+** NSPR's log service for your application.
+**
+** The special LogModule "all" enables all LogModules. To enable all
+** LogModule calls to PR_LOG(), say:
+**
+** set NSPR_LOG_MODULES=all:5
+**
+** The special LogModule name "sync" tells the NSPR log service to do
+** unbuffered logging.
+**
+** The special LogModule name "bufsize:<size>" tells NSPR to set the
+** log buffer to <size>.
+**
+** The environment variable NSPR_LOG_FILE specifies the log file to use
+** unless the default of "stderr" is acceptable. For MS Windows
+** systems, NSPR_LOG_FILE can be set to a special value: "WinDebug"
+** (case sensitive). This value causes PR_LOG() output to be written
+** using the Windows API OutputDebugString(). OutputDebugString()
+** writes to the debugger window; some people find this helpful.
+**
+**
+** To put log messages in your programs, use the PR_LOG macro:
+**
+** PR_LOG(<module>, <level>, (<printfString>, <args>*));
+**
+** Where <module> is the address of a PRLogModuleInfo structure, and
+** <level> is one of the levels defined by the enumeration:
+** PRLogModuleLevel. <args> is a printf() style of argument list. That
+** is: (fmtstring, ...).
+**
+** Example:
+**
+** main() {
+** PRIntn one = 1;
+** PRLogModuleInfo * myLm = PR_NewLogModule("gizmo");
+** PR_LOG( myLm, PR_LOG_ALWAYS, ("Log this! %d\n", one));
+** return;
+** }
+**
+** Note the use of printf() style arguments as the third agrument(s) to
+** PR_LOG().
+**
+** After compiling and linking you application, set the environment:
+**
+** set NSPR_LOG_MODULES=gizmo:5
+** set NSPR_LOG_FILE=logfile.txt
+**
+** When you execute your application, the string "Log this! 1" will be
+** written to the file "logfile.txt".
+**
+** Note to NSPR engineers: a number of PRLogModuleInfo structures are
+** defined and initialized in prinit.c. See this module for ideas on
+** what to log where.

+** predict and is as non-deterministic as the underlying platfrom can
+** provide.
+**
+** Inputs:
+** buf -- pointer to a caller supplied buffer to contain the
+** generated random number. buf must be at least as large as
+** is specified in the 'size' argument.
+**
+** size -- the requested size of the generated random number
+**
+** Outputs:
+** a random number provided in 'buf'.
+**
+** Returns:
+** PRSize value equal to the size of the random number actually

+** requested. A return value of zero means that PR_GetRandomNoise() is
+** not implemented on this platform, or there is no available noise
+** available to be returned at the time of the call.
+**
+** Restrictions:
+** Calls to PR_GetRandomNoise() may use a lot of CPU on some platforms.
+** Some platforms may block for up to a few seconds while they
+** accumulate some noise. Busy machines generate lots of noise, but
+** care is advised when using PR_GetRandomNoise() frequently in your
+** application.

+/*
+** prshm.h -- NSPR Shared Memory
+**
+** NSPR Named Shared Memory API provides a cross-platform named
+** shared-memory interface. NSPR Named Shared Memory is modeled on
+** similar constructs in Unix and Windows operating systems. Shared
+** memory allows multiple processes to access one or more common shared
+** memory regions, using it as an inter-process communication channel.
+**
+** Notes on Platform Independence:
+** NSPR Named Shared Memory is built on the native services offered
+** by most platforms. The NSPR Named Shared Memory API tries to
+** provide a least common denominator interface so that it works
+** across all supported platforms. To ensure that it works everywhere,
+** some platform considerations must be accomodated and the protocol
+** for using NSPR Shared Memory API must be observed.
+**
+** Protocol:
+** Multiple shared memories can be created using NSPR's Shared Memory
+** feature. For each named shared memory, as defined by the name
+** given in the PR_OpenSharedMemory() call, a protocol for using the
+** shared memory API is required to ensure desired behavior. Failing
+** to follow the protocol may yield unpredictable results.
+**
+** PR_OpenSharedMemory() will create the shared memory segment, if it
+** does not already exist, or open a connection that the existing
+** shared memory segment if it already exists.
+**
+** PR_AttachSharedMemory() should be called following
+** PR_OpenSharedMemory() to map the memory segment to an address in
+** the application's address space.
+**
+** PR_AttachSharedMemory() may be called to re-map a shared memory
+** segment after detaching the same PRSharedMemory object. Be
+** sure to detach it when done.
+**
+** PR_DetachSharedMemory() should be called to un-map the shared
+** memory segment from the application's address space.
+**
+** PR_CloseSharedMemory() should be called when no further use of the
+** PRSharedMemory object is required within a process. Following a
+** call to PR_CloseSharedMemory() the PRSharedMemory object is
+** invalid and cannot be reused.
+**
+** PR_DeleteSharedMemory() should be called before process
+** termination. After calling PR_DeleteSharedMemory() any further use
+** of the shared memory associated with the name may cause
+** unpredictable results.
+**
+** Files:
+** The name passed to PR_OpenSharedMemory() should be a valid filename
+** for a unix platform. 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 used to
+** define the namespace. On Windows, the name is significant, but
+** there is no file associated with 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 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:
+** 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 accomodate more
+** and/or larger shared memory segment(s).
+**
+** Security:
+** 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.
+**
+** Example:
+** The test case pr/tests/nameshm1.c provides an example of use as
+** well as testing the operation of NSPR's Named Shared Memory.

+** prshma.h -- NSPR Anonymous Shared Memory
+**
+** NSPR provides an anonymous shared memory based on NSPR's 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 accessable 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 processess
+** 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 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.
+**
+** First protocol.
+** Server:
+**
+** fm = PR_OpenAnonFileMap(dirName, size, FilemapProt);
+** addr = PR_MemMap(fm);
+** attr = PR_NewProcessAttr();
+** PR_ProcessAttrSetInheritableFileMap( attr, fm, shmname );
+** PR_CreateProcess(Client);
+** PR_DestroyProcessAttr(attr);
+** ... yadda ...
+** PR_MemUnmap( addr );
+** PR_CloseFileMap(fm);
+**
+**
+** Client:
+** ... started by server via PR_CreateProcess()
+** fm = PR_GetInheritedFileMap( shmname );
+** addr = PR_MemMap(fm);
+** ... yadda ...
+** PR_MemUnmap(addr);
+** PR_CloseFileMap(fm);
+**
+**
+** Second Protocol:
+** Server:
+**
+** fm = PR_OpenAnonFileMap(dirName, size, FilemapProt);
+** fmstring = PR_ExportFileMapAsString( fm );
+** addr = PR_MemMap(fm);
+** ... application specific technique to pass fmstring to child
+** ... yadda ... Server uses his own magic to create child
+** PR_MemUnmap( addr );
+** PR_CloseFileMap(fm);
+**
+**
+** Client:
+** ... started by server via his own magic
+** ... application specific technique to find fmstring from parent
+** fm = PR_ImportFileMapFromString( fmstring )
+** addr = PR_MemMap(fm);
+** ... yadda ...
+** PR_MemUnmap(addr);
+** PR_CloseFileMap(fm);
+**
+**
+** lth. 2-Jul-1999.
+**
+** Note: The second protocol was requested by NelsonB (7/1999); this is
+** to accomodate servers which already create their own child processes
+** using platform native methods.

+** API for NSPR threads. On some architectures (Mac OS Classic
+** notably) pre-emptibility is not guaranteed. Hard priority scheduling
+** is not guaranteed, so programming using priority based synchronization
+** is a no-no.
+**
+** NSPR threads are scheduled based loosely on their client set priority.
+** In general, a thread of a higher priority has a statistically better
+** chance of running relative to threads of lower priority. However,
+** NSPR uses multiple strategies to provide execution vehicles for thread
+** abstraction of various host platforms. As it turns out, there is little
+** NSPR can do to affect the scheduling attributes of "GLOBAL" threads.
+** However, a semblance of GLOBAL threads is used to implement "LOCAL"
+** threads. An arbitrary number of such LOCAL threads can be assigned to
+** a single GLOBAL thread.
+**
+** For scheduling, NSPR will attempt to run the highest priority LOCAL
+** thread associated with a given GLOBAL thread. It is further assumed
+** that the host OS will apply some form of "fair" scheduling on the
+** GLOBAL threads.
+**
+** Threads have a "system flag" which when set indicates the thread
+** doesn't count for determining when the process should exit (the
+** process exits when the last user thread exits).
+**
+** Threads also have a "scope flag" which controls whether the threads
+** are scheduled in the local scope or scheduled by the OS globally. This
+** indicates whether a thread is permanently bound to a native OS thread.
+** An unbound thread competes for scheduling resources in the same process.
+**
+** Another flag is "state flag" which control whether the thread is joinable.
+** It allows other threads to wait for the created thread to reach completion.
+**
+** Threads can have "per-thread-data" attached to them. Each thread has a
+** per-thread error number and error string which are updated when NSPR
+** operations fail.

+** prtrace.h -- NSPR's Trace Facility.
+**
+** The Trace Facility provides a means to trace application
+** program events within a process. When implementing an
+** application program an engineer may insert a "Trace" function
+** call, passing arguments to be traced. The "Trace" function
+** combines the user trace data with identifying data and
+** writes this data in time ordered sequence into a circular
+** in-memory buffer; when the buffer fills, it wraps.
+**
+** Functions are provided to set and/or re-configure the size of
+** the trace buffer, control what events are recorded in the
+** buffer, enable and disable tracing based on specific user
+** supplied data and other control functions. Methods are provided
+** to record the trace entries in the in-memory trace buffer to
+** a file.
+**
+** Tracing may cause a performance degredation to the application
+** depending on the number and placement of calls to the tracing
+** facility. When tracing is compiled in and all tracing is
+** disabled via the runtime controls, the overhead should be
+** minimal. ... Famous last words, eh?
+**
+** When DEBUG is defined at compile time, the Trace Facility is
+** compiled as part of NSPR and any application using NSPR's
+** header files will have tracing compiled in. When DEBUG is not
+** defined, the Trace Facility is not compiled into NSPR nor
+** exported in its header files. If the Trace Facility is
+** desired in a non-debug build, then FORCE_NSPR_TRACE may be
+** defined at compile time for both the optimized build of NSPR
+** and the application. NSPR and any application using NSPR's
+** Trace Facility must be compiled with the same level of trace
+** conditioning or unresolved references may be realized at link
+** time.
+**
+** For any of the Trace Facility methods that requires a trace
+** handle as an input argument, the caller must ensure that the
+** trace handle argument is valid. An invalid trace handle
+** argument may cause unpredictable results.
+**
+** Trace Facility methods are thread-safe and SMP safe.
+**
+** Users of the Trace Facility should use the defined macros to
+** invoke trace methods, not the function calls directly. e.g.
+** PR_TRACE( h1,0,1,2, ...); not PR_Trace(h1,0,1,2, ...);
+**
+** Application designers should be aware of the effects of
+** debug and optimized build differences when using result of the
+** Trace Facility macros in expressions.

+** DESCRIPTION:
+** PR_RecordTraceEntries() causes entries in the in-memory trace

+**
+** When PR_RecordTraceEntries() is called from an application

+** environment, no recording of trace entries occurs. When
+** NSPR_TRACE_LOG is defined, the value of its definition must be
+** the filename of the file to receive the trace entry buffer.
+**
+** PR_RecordTraceEntries() attempts to record the in-memory
+** buffer to a file, subject to the setting of the environment
+** variable NSPR_TRACE_LOG. It is possible because of system
+** load, the thread priority of the recording thread, number of

+**
+** To make sure that PR_fprintf(), and related functions, work correctly,

+** .EXE. To do this, a hack is placed in _MD_Write() such that the
+** fd for stdio handles results in a call to the .EXE.
+**
+** file w16stdio.c contains the functions that get called from NSPR
+** to do the actual I/O. w16stdio.o must be statically linked with
+** any application needing stdio for Win16.
+**
+** The address of these functions must be made available to the .DLL
+** so he can call back to the .EXE. To do this, function
+** PR_MD_RegisterW16StdioCallbacks() is called from the .EXE.
+** The arguments are the functions defined in w16stdio.c
+** At runtime, MD_Write() calls the registered functions, if any
+** were registered.
+**
+** prinit.h contains a macro PR_STDIO_INIT() that calls the registration
+** function for Win16; For other platforms, the macro is a No-Op.
+**
+** Note that stdio is not operational at all on Win16 GUI applications.

+** .DLL for command line applications only. NSPR's test cases are
