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.

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. +** +**/ + +/**********************************************************************/ +/************************* TYPES AND CONSTANTS ************************/ +/**********************************************************************/ + +/* + * PRLanguageCode -- + * + * NSPR represents a language code as a non-negative integer. + * Languages 0 is always "i-default" the language you get without + * explicit negotiation.

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.

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. +** +** lth. 18-Aug-1999. +*/ + +#ifndef prshm_h___ +#define prshm_h___ + +#include "prtypes.h" +#include "prio.h" + +PR_BEGIN_EXTERN_C + +/* +** Declare opaque type PRSharedMemory. +*/ +typedef struct PRSharedMemory PRSharedMemory; + +/* +** FUNCTION: PR_OpenSharedMemory() +** +** DESCRIPTION: +** PR_OpenSharedMemory() creates a new shared-memory segment or +** associates a previously created memory segment with name. +** +** When parameter create is (PR_SHM_EXCL | PR_SHM_CREATE) and the +** shared memory already exists, the function returns NULL with the +** error set to PR_FILE_EXISTS_ERROR. +** +** When parameter create is PR_SHM_CREATE and the shared memory +** already exists, a handle to that memory segment is returned.
