|

|
- * 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
