PTHREADS-WIN32 RELEASE 2.8.0 (2006-12-22)
|

Web Site: http://sources.redhat.com/pthreads-win32/

Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
|
||
|
|
|
||
|
|
|
||
|
|
We are pleased to announce the availability of a new release of
|
||
|
|
Pthreads-win32, an Open Source Software implementation of the
|
||
|
|
Threads component of the POSIX 1003.1 2001 Standard for Microsoft's
|
||
|
|
Win32 environment. Some functions from other sections of POSIX
|
||
|
|
1003.1 2001 are also supported including semaphores and scheduling
|
||
|
|
functions.
|
||
|
|
|
||
|
|
Some common non-portable functions are also implemented for
|
||
|
|
additional compatibility, as are a few functions specific
|
||
|
|
to pthreads-win32 for easier integration with Win32 applications.
|
||
|
|
|
||
|
|
Pthreads-win32 is free software, distributed under the GNU Lesser
|
||
|
|
General Public License (LGPL).

Acknowledgements
|
||
|
|
----------------
|
||
|
|
This library is based originally on a Win32 pthreads
|
||
|
|
implementation contributed by John Bossom <John.Bossom@cognos.com>.
|
||
|
|
|
||
|
|
The implementation of Condition Variables uses algorithms developed
|
||
|
|
by Alexander Terekhov and Louis Thomas.
|
||
|
|
|
||
|
|
The implementation of POSIX mutexes has been improved by Thomas Pfaff
|
||
|
|
and later by Alexander Terekhov.
|
||
|
|
|
||
|
|
The implementation of Spinlocks and Barriers was contributed
|
||
|
|
by Ross Johnson.
|
||
|
|
|
||
|
|
The implementation of read/write locks was contributed by
|
||
|
|
Aurelio Medina and improved by Alexander Terekhov.
|
||
|
|
|
||
|
|
Many others have contributed significant time and effort to solve crutial
|
||
|
|
problems in order to make the library workable, robust and reliable.
|
||
|
|
|
||
|
|
Thanks to Xavier Leroy for granting permission to use and modify his
|
||
|
|
LinuxThreads manual pages.
|
||
|
|
|
||
|
|
Thanks to The Open Group for making the Single Unix Specification
|
||
|
|
publicly available - many of the manual pages included in the package
|
||
|
|
were extracted from it.
|
||
|
|
|
||
|
|
There is also a separate CONTRIBUTORS file. This file and others are
|
||
|
|
on the web site:
|
||

|
|
||
|
|
http://sources.redhat.com/pthreads-win32
|
||
|
|
|
||
|
|
As much as possible, the ChangeLog file acknowledges contributions to the
|
||
|
|
code base in more detail.

Availability
|
||
|
|
------------
|
||
|
|
|
||
|
|
The prebuilt DLL, export libs (for both MSVC and Mingw32), and the header
|
||
|
|
files (pthread.h, semaphore.h, sched.h) are available along with the
|
||
|
|
complete source code.
|
||
|
|
|
||
|
|
The source code can be found at:

Mailing List
|
||
|
|
------------
|
||
|
|
|
||
|
|
There is a mailing list for discussing pthreads on Win32. To join,
|
||
|
|
send email to:
|
||
|
|
|

pthreads-win32-subscribe@sourceware.cygnus.com

Application Development Environments
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
See the README file for more information.
|
||
|
|
|
||
|
|
MSVC:
|
||
|
|
MSVC using SEH works. Distribute pthreadVSE.dll with your application.
|
||
|
|
MSVC using C++ EH works. Distribute pthreadVCE.dll with your application.
|
||
|
|
MSVC using C setjmp/longjmp works. Distribute pthreadVC.dll with your application.
|
||
|
|
|
||
|
|
|
||
|
|
Mingw32:
|
||
|
|
See the FAQ, Questions 6 and 10.
|
||
|
|
|
||
|
|
Mingw using C++ EH works. Distribute pthreadGCE.dll with your application.
|
||
|
|
Mingw using C setjmp/longjmp works. Distribute pthreadGC.dll with your application.
|
||
|
|
|
||
|
|
|
||
|
|
Cygwin: (http://sourceware.cygnus.com/cygwin/)
|
||
|
|
Developers using Cygwin will not need pthreads-win32 since it has POSIX threads
|
||
|
|
support. Refer to its documentation for details and extent.
|
||
|
|
|
||
|
|
|
||
|
|
UWIN:
|
||
|
|
UWIN is a complete Unix-like environment for Windows from AT&T. Pthreads-win32
|
||
|
|
doesn't currently support UWIN (and vice versa), but that may change in the
|
||
|
|
future.
|
||
