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.
374 * pthread_mutexattr_getprotocol +
375 * pthread_mutexattr_setprotocol +
376 *
377 * _POSIX_THREAD_PRIO_PROTECT (== -1)
378 * If == 200112L, you can create priority ceiling mutexes
379 * Indicates the availability of:
380 * pthread_mutex_getprioceiling
381 * pthread_mutex_setprioceiling
382 * pthread_mutexattr_getprioceiling
383 * pthread_mutexattr_getprotocol +
384 * pthread_mutexattr_setprioceiling
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
394 * pthread_condattr_getpshared
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
409 *
410 * + These functions provide both 'inherit' and/or
411 * 'protect' protocol, based upon these macro
412 * settings.
