* in the cancelation and thread exit implementations and therefore won't

* do stack unwinding if linked to applications that have it (e.g.
|
|
* C++ apps). This is currently consistent with most/all commercial Unix

|
|
*
|
|
*
|
|
* Module: pthread.h
|
|
*
|
|
* Purpose:
|
|
* Provides an implementation of PThreads based upon the
|
|
* standard:
|
|
*
|
|
* POSIX 1003.1-2001
|
|
* and
|
|
* The Single Unix Specification version 3
|
|
*
|
|
* (these two are equivalent)
|
|
*
|
|
* in order to enhance code portability between Windows,
|
|
* various commercial Unix implementations, and Linux.
|
|
*
|
|
* See the ANNOUNCE file for a full list of conforming
|
|
* routines and defined constants, and a list of missing
|
|
* routines and constants not defined in this implementation.
|
|
*
|
|
* Authors:
|
|
* There have been many contributors to this library.
|
|
* The initial implementation was contributed by
|
|
* John Bossom, and several others have provided major
|
|
* sections or revisions of parts of the implementation.
|
|
* Often significant effort has been contributed to
|
|
* find and fix important bugs and other problems to
|
|
* improve the reliability of the library, which sometimes
|
|
* is not reflected in the amount of code which changed as
|
|
* result.
|
|
* As much as possible, the contributors are acknowledged
|
|
* in the ChangeLog file in the source code distribution
|
|
* where their changes are noted in detail.
|
|
*
|
|
* Contributors are listed in the CONTRIBUTORS file.
|
|
*
|
|
* As usual, all bouquets go to the contributors, and all
|
|
* brickbats go to the project maintainer.
|
|
*
|
|
* Maintainer:
|
|
* The code base for this project is coordinated and
|
|
* eventually pre-tested, packaged, and made available by
|
|
*
|
|
* Ross Johnson <rpj@callisto.canberra.edu.au>
|
|
*
|
|
* QA Testers:
|
|
* Ultimately, the library is tested in the real world by
|
|
* a host of competent and demanding scientists and
|
|
* engineers who report bugs and/or provide solutions
|
|
* which are then fixed or incorporated into subsequent
|
|
* versions of the library. Each time a bug is fixed, a
|
|
* test case is written to prove the fix and ensure
|
|
* that later changes to the code don't reintroduce the
|
|
* same error. The number of test cases is slowly growing
|
|
* and therefore so is the code reliability.
|
|
*
|
|
* Compliance:
|
|
* See the file ANNOUNCE for the list of implemented
|
|
* and not-implemented routines and defined options.
|
|
* Of course, these are all defined is this file as well.
|
|
*
|
|
* Web site:
|
|
* The source code and other information about this library
|
|
* are available from
|
|
*
|
|
* http://sources.redhat.com/pthreads-win32/

* POSIX 1003.1-2001 Options
|
|
* =========================
|
|
*
|
|
* Options are normally set in <unistd.h>, which is not provided
|
|
* with pthreads-win32.
|
|
*
|
|
* For conformance with the Single Unix Specification (version 3), all of the
|
|
* options below are defined, and have a value of either -1 (not supported)
|
|
* or 200112L (supported).
|
|
*
|
|
* These options can neither be left undefined nor have a value of 0, because
|
|
* either indicates that sysconf(), which is not implemented, may be used at
|
|
* runtime to check the status of the option.
|
|
*
|
|
* _POSIX_THREADS (== 200112L)
|
|
* If == 200112L, you can use threads
|
|
*
|
|
* _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
|
|
* If == 200112L, you can control the size of a thread's
|
|
* stack
|
|
* pthread_attr_getstacksize
|
|
* pthread_attr_setstacksize
|
|
*
|
|
* _POSIX_THREAD_ATTR_STACKADDR (== -1)
|
|
* If == 200112L, you can allocate and control a thread's
|
|
* stack. If not supported, the following functions
|
|
* will return ENOSYS, indicating they are not
|
|
* supported:
|
|
* pthread_attr_getstackaddr
|
|
* pthread_attr_setstackaddr
|
|
*
|
|
* _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
|
|
* If == 200112L, you can use realtime scheduling.
|
|
* This option indicates that the behaviour of some
|
|
* implemented functions conforms to the additional TPS
|
|
* requirements in the standard. E.g. rwlocks favour
|
|
* writers over readers when threads have equal priority.
|
|
*
|
|
* _POSIX_THREAD_PRIO_INHERIT (== -1)
|
|
* If == 200112L, you can create priority inheritance
|
|
* mutexes.
|
|
* pthread_mutexattr_getprotocol +
|
|
* pthread_mutexattr_setprotocol +
|
|
*
|
|
* _POSIX_THREAD_PRIO_PROTECT (== -1)
|
|
* If == 200112L, you can create priority ceiling mutexes
|
|
* Indicates the availability of:
|
|
* pthread_mutex_getprioceiling
|
|
* pthread_mutex_setprioceiling
|
|
* pthread_mutexattr_getprioceiling
|
|
* pthread_mutexattr_getprotocol +
|
|
* pthread_mutexattr_setprioceiling
|
|
* pthread_mutexattr_setprotocol +
|
|
*
|
|
* _POSIX_THREAD_PROCESS_SHARED (== -1)
|
|
* If set, you can create mutexes and condition
|
|
* variables that can be shared with another
|
|
* process.If set, indicates the availability
|
|
* of:
|
|
* pthread_mutexattr_getpshared
|
|
* pthread_mutexattr_setpshared
|
|
* pthread_condattr_getpshared
|
|
* pthread_condattr_setpshared
|
|
*
|
|
* _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
|
|
* If == 200112L you can use the special *_r library
|
|
* functions that provide thread-safe behaviour
|
|
*
|
|
* _POSIX_READER_WRITER_LOCKS (== 200112L)
|
|
* If == 200112L, you can use read/write locks
|
|
*
|
|
* _POSIX_SPIN_LOCKS (== 200112L)
|
|
* If == 200112L, you can use spin locks
|
|
*
|
|
* _POSIX_BARRIERS (== 200112L)
|
|
* If == 200112L, you can use barriers
|
|
*
|
|
* + These functions provide both 'inherit' and/or
|
|
* 'protect' protocol, based upon these macro
|
|
* settings.
