122 *
123 * Module: pthread.h
124 *
125 * Purpose:
126 *      Provides an implementation of PThreads based upon the
127 *      standard:
128 *
129 *              POSIX 1003.1-2001
130 *  and
131 *    The Single Unix Specification version 3
132 *
133 *    (these two are equivalent)
134 *
135 *      in order to enhance code portability between Windows,
136 *  various commercial Unix implementations, and Linux.
137 *
138 *      See the ANNOUNCE file for a full list of conforming
139 *      routines and defined constants, and a list of missing
140 *      routines and constants not defined in this implementation.
141 *
142 * Authors:
143 *      There have been many contributors to this library.
144 *      The initial implementation was contributed by
145 *      John Bossom, and several others have provided major
146 *      sections or revisions of parts of the implementation.
147 *      Often significant effort has been contributed to
148 *      find and fix important bugs and other problems to
149 *      improve the reliability of the library, which sometimes
150 *      is not reflected in the amount of code which changed as
151 *      result.
152 *      As much as possible, the contributors are acknowledged
153 *      in the ChangeLog file in the source code distribution
154 *      where their changes are noted in detail.
155 *
156 *      Contributors are listed in the CONTRIBUTORS file.
157 *
158 *      As usual, all bouquets go to the contributors, and all
159 *      brickbats go to the project maintainer.
160 *
161 * Maintainer:
162 *      The code base for this project is coordinated and
163 *      eventually pre-tested, packaged, and made available by
164 *
165 *              Ross Johnson <rpj@callisto.canberra.edu.au>
166 *
167 * QA Testers:
168 *      Ultimately, the library is tested in the real world by
169 *      a host of competent and demanding scientists and
170 *      engineers who report bugs and/or provide solutions
171 *      which are then fixed or incorporated into subsequent
172 *      versions of the library. Each time a bug is fixed, a
173 *      test case is written to prove the fix and ensure
174 *      that later changes to the code don't reintroduce the
175 *      same error. The number of test cases is slowly growing
176 *      and therefore so is the code reliability.
177 *
178 * Compliance:
179 *      See the file ANNOUNCE for the list of implemented
180 *      and not-implemented routines and defined options.
181 *      Of course, these are all defined is this file as well.
182 *
183 * Web site:
184 *      The source code and other information about this library
185 *      are available from
186 *
187 *              http://sources.redhat.com/pthreads-win32/

333 * POSIX 1003.1-2001 Options
334 * =========================
335 *
336 * Options are normally set in <unistd.h>, which is not provided
337 * with pthreads-win32.
338 *
339 * For conformance with the Single Unix Specification (version 3), all of the
340 * options below are defined, and have a value of either -1 (not supported)
341 * or 200112L (supported).
342 *
343 * These options can neither be left undefined nor have a value of 0, because
344 * either indicates that sysconf(), which is not implemented, may be used at
345 * runtime to check the status of the option.
346 *
347 * _POSIX_THREADS (== 200112L)
348 *                      If == 200112L, you can use threads
349 *
350 * _POSIX_THREAD_ATTR_STACKSIZE (== 200112L)
351 *                      If == 200112L, you can control the size of a thread's
352 *                      stack
353 *                              pthread_attr_getstacksize
354 *                              pthread_attr_setstacksize
355 *
356 * _POSIX_THREAD_ATTR_STACKADDR (== -1)
357 *                      If == 200112L, you can allocate and control a thread's
358 *                      stack. If not supported, the following functions
359 *                      will return ENOSYS, indicating they are not
360 *                      supported:
361 *                              pthread_attr_getstackaddr
362 *                              pthread_attr_setstackaddr
363 *
364 * _POSIX_THREAD_PRIORITY_SCHEDULING (== -1)
365 *                      If == 200112L, you can use realtime scheduling.
366 *                      This option indicates that the behaviour of some
367 *                      implemented functions conforms to the additional TPS
368 *                      requirements in the standard. E.g. rwlocks favour
369 *                      writers over readers when threads have equal priority.
370 *
371 * _POSIX_THREAD_PRIO_INHERIT (== -1)
372 *                      If == 200112L, you can create priority inheritance
373 *                      mutexes.

385 *                              pthread_mutexattr_setprotocol     +
386 *
387 * _POSIX_THREAD_PROCESS_SHARED (== -1)
388 *                      If set, you can create mutexes and condition
389 *                      variables that can be shared with another
390 *                      process.If set, indicates the availability
391 *                      of:
392 *                              pthread_mutexattr_getpshared
393 *                              pthread_mutexattr_setpshared

395 *                              pthread_condattr_setpshared
396 *
397 * _POSIX_THREAD_SAFE_FUNCTIONS (== 200112L)
398 *                      If == 200112L you can use the special *_r library
399 *                      functions that provide thread-safe behaviour
400 *
401 * _POSIX_READER_WRITER_LOCKS (== 200112L)
402 *                      If == 200112L, you can use read/write locks
403 *
404 * _POSIX_SPIN_LOCKS (== 200112L)
405 *                      If == 200112L, you can use spin locks
406 *
407 * _POSIX_BARRIERS (== 200112L)
408 *                      If == 200112L, you can use barriers
