- * -------------------------------------------------------------

- *
- * 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_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.

+ * -------------------------------------------------------------

+ *

+ *

+ * 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/

+ * For conformance with the Single Unix Specification (version 3), all of the

+ *

+ * 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)

+ *                      stack. If not supported, the following functions

+ *                      will return ENOSYS, indicating they are not

+ *                      supported:

+ *

+ * _POSIX_THREAD_PRIO_INHERIT (== -1)

+ *                      If == 200112L, you can create priority inheritance

+ *                      mutexes.

+ *

+ * _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
