+ * -------------------------------------------------------------
+ *
+ *
+ * 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.
