  1.      PTHREADS-WIN32 RELEASE 2.8.0 (2006-12-22)
  2.      -----------------------------------------
  3.  Web Site: http://sources.redhat.com/pthreads-win32/
  4. FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
  5.  Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
  8. We are pleased to announce the availability of a new release of
  9. Pthreads-win32, an Open Source Software implementation of the
  10. Threads component of the POSIX 1003.1 2001 Standard for Microsoft's
  11. Win32 environment. Some functions from other sections of POSIX
  12. 1003.1 2001 are also supported including semaphores and scheduling
  13. functions.
  15. Some common non-portable functions are also implemented for
  16. additional compatibility, as are a few functions specific
  17. to pthreads-win32 for easier integration with Win32 applications.
  19. Pthreads-win32 is free software, distributed under the GNU Lesser
  20. General Public License (LGPL).
  23. Acknowledgements
  24. ----------------
  25. This library is based originally on a Win32 pthreads
  26. implementation contributed by John Bossom <John.Bossom@cognos.com>.
  28. The implementation of Condition Variables uses algorithms developed
  29. by Alexander Terekhov and Louis Thomas.
  31. The implementation of POSIX mutexes has been improved by Thomas Pfaff
  32. and later by Alexander Terekhov.
  34. The implementation of Spinlocks and Barriers was contributed
  35. by Ross Johnson.
  37. The implementation of read/write locks was contributed by
  38. Aurelio Medina and improved by Alexander Terekhov.
  40. Many others have contributed significant time and effort to solve crutial
  41. problems in order to make the library workable, robust and reliable.
  43. Thanks to Xavier Leroy for granting permission to use and modify his
  44. LinuxThreads manual pages.
  46. Thanks to The Open Group for making the Single Unix Specification
  47. publicly available - many of the manual pages included in the package
  48. were extracted from it.
  50. There is also a separate CONTRIBUTORS file. This file and others are
  51. on the web site:
  53. http://sources.redhat.com/pthreads-win32
  55. As much as possible, the ChangeLog file acknowledges contributions to the
  56. code base in more detail.

  361. Availability
  362. ------------ 
  364. The prebuilt DLL, export libs (for both MSVC and Mingw32), and the header
  365. files (pthread.h, semaphore.h, sched.h) are available along with the
  366. complete source code.
  368. The source code can be found at:
  370. ftp://sources.redhat.com/pub/pthreads-win32
  372. and as individual source code files at
  374. ftp://sources.redhat.com/pub/pthreads-win32/source
  376. The pre-built DLL, export libraries and include files can be found at:
  378. ftp://sources.redhat.com/pub/pthreads-win32/dll-latest
  381.       
  382. Mailing List 
  383. ------------  
  384.       
  385. There is a mailing list for discussing pthreads on Win32. To join,
  386. send email to:
  388. pthreads-win32-subscribe@sourceware.cygnus.com
  389.       
  391. Application Development Environments
  392. ------------------------------------
  394. See the README file for more information.
  395.       
  396. MSVC:
  397. MSVC using SEH works. Distribute pthreadVSE.dll with your application.
  398. MSVC using C++ EH works. Distribute pthreadVCE.dll with your application.
  399. MSVC using C setjmp/longjmp works. Distribute pthreadVC.dll with your application.
  402. Mingw32:
  403. See the FAQ, Questions 6 and 10.
  405. Mingw using C++ EH works. Distribute pthreadGCE.dll with your application.
  406. Mingw using C setjmp/longjmp works. Distribute pthreadGC.dll with your application.
  409. Cygwin: (http://sourceware.cygnus.com/cygwin/)
  410. Developers using Cygwin will not need pthreads-win32 since it has POSIX threads
  411. support. Refer to its documentation for details and extent.
  414. UWIN:
  415. UWIN is a complete Unix-like environment for Windows from AT&T. Pthreads-win32
  416. doesn't currently support UWIN (and vice versa), but that may change in the
  417. future.
  419. Generally:
  420. For convenience, the following pre-built files are available on the FTP site
  421. (see Availability above):
  423. pthread.h - for POSIX 1c threads
  424. semaphore.h - for POSIX 1b semaphores
  425. sched.h  - for POSIX 1b scheduling
  426. pthreadVCE.dll - built with MSVC++ compiler using C++ EH
  427. pthreadVCE.lib
  428. pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
  429. pthreadVC.lib
  430. pthreadVSE.dll - built with MSVC compiler using SEH
  431. pthreadVSE.lib
  432. pthreadGCE.dll - built with Mingw32 G++ 2.95.2-1
  433. pthreadGC.dll - built with Mingw32 GCC 2.95.2-1 using setjmp/longjmp
  434. libpthreadGCE.a - derived from pthreadGCE.dll
  435. libpthreadGC.a - derived from pthreadGC.dll
  436. gcc.dll  - needed if distributing applications that use
  437.   pthreadGCE.dll (but see the FAQ Q 10 for the latest
  438.   related information)
  440. These are the only files you need in order to build POSIX threads
  441. applications for Win32 using either MSVC or Mingw32.
  443. See the FAQ file in the source tree for additional information.
  446. Documentation
  447. -------------
  449. For the authoritative reference, see the online POSIX
  450. standard reference at:
  452.        http://www.OpenGroup.org
  454. For POSIX Thread API programming, several reference books are
  455. available:
  457.        Programming with POSIX Threads
  458.        David R. Butenhof
  459.        Addison-Wesley (pub)
  461.        Pthreads Programming
  462.        By Bradford Nichols, Dick Buttlar & Jacqueline Proulx Farrell
  463.        O'Reilly (pub)
  465. On the web: see the links at the bottom of the pthreads-win32 site:
  467.        http://sources.redhat.com/pthreads-win32/
  469.        Currently, there is no documentation included in the package apart
  470.        from the copious comments in the source code.
  474. Enjoy!
