|

- * 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 <[email protected]>
|
|
|
- *
|
|
|
- * 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

|
|
|
- * =========================
|
|
|
- *
|
|
|
- * 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.

|
|
|

|
|
|
+ * 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 <[email protected]>
|
|
|
+ *
|
|
|
+ * 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.

+ * 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_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_getpshared
|
|
|
+ * 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.
