- * -------------------------------------------------------------
- *
- *
- * 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 <rpj@callisto.canberra.edu.au>
- *
- * 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
- *
- * http://sources.redhat.com/pthreads-win32/

- * 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_getprioceiling
- * pthread_mutexattr_getprotocol +
- * pthread_mutexattr_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.

+ * -------------------------------------------------------------
+ *
+ *
+ * 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 <rpj@callisto.canberra.edu.au>
+ *
+ * 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
+ *
+ * http://sources.redhat.com/pthreads-win32/

+ * 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_getprioceiling
+ * pthread_mutexattr_getprotocol +
+ * pthread_mutexattr_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.
