00058  * depending upon whether the library was built
00059  * using SEH, C++, or C. For example, a library built

00069  * do stack unwinding if linked to applications that have it (e.g.
00070  * C++ apps). This is currently consistent with most/all commercial Unix

00122  *
00123  * Module: pthread.h
00124  *
00125  * Purpose:
00126  *      Provides an implementation of PThreads based upon the
00127  *      standard:
00128  *
00129  *              POSIX 1003.1-2001
00130  *  and
00131  *    The Single Unix Specification version 3
00132  *
00133  *    (these two are equivalent)
00134  *
00135  *      in order to enhance code portability between Windows,
00136  *  various commercial Unix implementations, and Linux.
00137  *
00138  *      See the ANNOUNCE file for a full list of conforming
00139  *      routines and defined constants, and a list of missing
00140  *      routines and constants not defined in this implementation.
00141  *
00142  * Authors:
00143  *      There have been many contributors to this library.
00144  *      The initial implementation was contributed by
00145  *      John Bossom, and several others have provided major
00146  *      sections or revisions of parts of the implementation.
00147  *      Often significant effort has been contributed to
00148  *      find and fix important bugs and other problems to
00149  *      improve the reliability of the library, which sometimes
00150  *      is not reflected in the amount of code which changed as
00151  *      result.
00152  *      As much as possible, the contributors are acknowledged
00153  *      in the ChangeLog file in the source code distribution
00154  *      where their changes are noted in detail.
00155  *
00156  *      Contributors are listed in the CONTRIBUTORS file.
00157  *
00158  *      As usual, all bouquets go to the contributors, and all
00159  *      brickbats go to the project maintainer.
00160  *
00161  * Maintainer:
00162  *      The code base for this project is coordinated and
00163  *      eventually pre-tested, packaged, and made available by
00164  *
00165  *              Ross Johnson <rpj@callisto.canberra.edu.au>
00166  *
00167  * QA Testers:
00168  *      Ultimately, the library is tested in the real world by
00169  *      a host of competent and demanding scientists and
00170  *      engineers who report bugs and/or provide solutions
00171  *      which are then fixed or incorporated into subsequent
00172  *      versions of the library. Each time a bug is fixed, a
00173  *      test case is written to prove the fix and ensure
00174  *      that later changes to the code don't reintroduce the
00175  *      same error. The number of test cases is slowly growing
00176  *      and therefore so is the code reliability.
00177  *
00178  * Compliance:
00179  *      See the file ANNOUNCE for the list of implemented
00180  *      and not-implemented routines and defined options.
00181  *      Of course, these are all defined is this file as well.
00182  *
00183  * Web site:
00184  *      The source code and other information about this library
00185  *      are available from

00333  * POSIX 1003.1-2001 Options
00334  * =========================
00335  *
00336  * Options are normally set in <unistd.h>, which is not provided
00337  * with pthreads-win32.
00338  *
00339  * For conformance with the Single Unix Specification (version 3), all of the
00340  * options below are defined, and have a value of either -1 (not supported)
00341  * or 200112L (supported).
00342  *
00343  * These options can neither be left undefined nor have a value of 0, because
00344  * either indicates that sysconf(), which is not implemented, may be used at
00345  * runtime to check the status of the option.
00346  *
00347  * _POSIX_THREADS (== 200112L)
00348  *                      If == 200112L, you can use threads
00349  *
00350  * _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
00351  *                      If == 200112L, you can control the size of a thread's
00352  *                      stack
00353  *                              pthread_attr_getstacksize
00354  *                              pthread_attr_setstacksize
00355  *
00356  * _POSIX_THREAD_ATTR_STACKADDR (== -1)
00357  *                      If == 200112L, you can allocate and control a thread's
00358  *                      stack. If not supported, the following functions
00359  *                      will return ENOSYS, indicating they are not
00360  *                      supported:

00363  *
00364  * _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
00365  *                      If == 200112L, you can use realtime scheduling.
00366  *                      This option indicates that the behaviour of some
00367  *                      implemented functions conforms to the additional TPS
00368  *                      requirements in the standard. E.g. rwlocks favour
00369  *                      writers over readers when threads have equal priority.
00370  *
00371  * _POSIX_THREAD_PRIO_INHERIT (== -1)
00372  *                      If == 200112L, you can create priority inheritance
00373  *                      mutexes.

00396  *

00398  *                      If == 200112L you can use the special *_r library

00409  *
00410  *      + These functions provide both 'inherit' and/or
