/*
 * -------------------------------------------------------------
 *
 *
 * 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.
