46 | * The code here and within the library aims to work |

52 | * C |

53 | * C++ |

56 | * "return", "exit", "break", or "continue" will |
---|
57 | * lead to different behaviour amongst applications |
---|
58 | * depending upon whether the library was built |
---|
59 | * using SEH, C++, or C. For example, a library built |
---|
60 | * with SEH will call the cleanup routine, while both |

68 | * in the cancelation and thread exit implementations and therefore won't |

69 | * do stack unwinding if linked to applications that have it (e.g. |

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 |

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 |

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 |
