/* There are three implementations of cancel cleanup.

* The code here and within the library aims to work

*
* The three implementations are:
*
* WIN32 SEH
* C
* C++
*
* Please note that exiting a push/pop block via
* "return", "exit", "break", or "continue" will
* lead to different behaviour amongst applications
* depending upon whether the library was built
* using SEH, C++, or C. For example, a library built
* with SEH will call the cleanup routine, while both
* C++ and C built versions will not.
*/
/*
* Define defaults for cleanup code.
* Note: Unless the build explicitly defines one of the following, then
* we default to standard C style cleanup. This style uses setjmp/longjmp
* in the cancelation and thread exit implementations and therefore won't
* do stack unwinding if linked to applications that have it (e.g.
* C++ apps). This is currently consistent with most/all commercial Unix
* POSIX threads implementations.

/*
* -------------------------------------------------------------
*
*
* 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/
