/*
 * -------------------------------------------------------------
 *
 *
 * 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 <[e-mail]>
 *
 * 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/
