+ PTHREADS-WIN32 SNAPSHOT 2000-08-10
+ ----------------------------------
+ Web Site: http://sources.redhat.com/pthreads-win32/
+ FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
+ Coordinator: Ross Johnson <rpj@ise.canberra.edu.au>
+
+
+We are pleased to announce the availability of a new snapshot of
+Pthreads-win32, an Open Source Software (OSS) implementation of the
+Threads component of the POSIX 1003.1c 1995 Standard for Microsoft's
+Win32 environment. Some functions from POSIX 1003.1b are also
+supported including semaphores. Other related functions include
+the set of read-write lock functions.
+
+Pthreads-win32 is free software, distributed under the GNU Library
+General Public License (LGPL).
+
+Please see the 'Acknowledgements' section at the end of this
+announcement for the list of contributors.
+
+
+Change Summary (since the last snapshot)
+----------------------------------------
+
+(See the ChangeLog file for details.)
+
+New:
+- asynchronous cancelation on X86 (Jason Nye)
+- Makefile compatible with MS nmake to replace
+ buildlib.bat
+- GNUmakefile for Mingw32
+- tests/Makefile for MS nmake replaces runall.bat
+- tests/GNUmakefile for Mingw32
+
+Bugs fixed:
+- kernel32 load/free problem
+- attempt to hide internel exceptions from application
+ exception handlers (__try/__except and try/catch blocks)
+- Win32 thread handle leakage bug
+ (David Baggett/Paul Redondo/Eyal Lebedinsky)
+
+Some new tests have been added.
+
+
+Known bugs in this snapshot
+---------------------------
+
+1. Running the test "join1.c" with the library built with Mingw32
+and the GNUmakefile included, the test fails with a segmentation (invalid
+page access) exception. The fault appears to be in the assembler code
+emmitted by the compiler [to handle exception contexts] at the
+end of the try block in _pthread_threadStart().
+
+2. There are problems with using the libpthread32.a file with the
+VC++ SEH version of pthread.dll. The cleanup1.c test fails and the
+eyal1.c test gives suspect results.
+
+3. I have not been able to build with VC++ using C++ EH. This is a
+maintainer problem who doesn't think he's doing it right. Consequently
+there may also be basic parser errors and warnings to be cleaned
+up in the code.
+
+4. Due to what is believed to be a C++ compliance error in VC++,
+if your application contains catch(...) blocks in your POSIX threads
+then you will need to replace the "catch(...)" with the macro
+"PtW32Catch", eg.
+
+ #ifdef PtW32Catch
+ PtW32Catch {
+ ...
+ }
+ #else
+ catch(...) {
+ ...
+ }
+ #endif
+
+Otherwise neither pthreads cancelation nor pthread_exit() will work
+reliably.

+complete source code.
+
+The source code can be found at:
+
+ ftp://sourcs.redhat.com/pub/pthreads-win32
+
+and as individual source code files at
+
+ ftp://sources.redhat.com/pub/pthreads-win32/source

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

+
+
+Application Development Environments
+------------------------------------
+
+MSVC:
+MSVC using SEH works.
+MSVC using C++ EH not tested.
+
+Mingw32: (ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/egcs-1.1.1/)
+Mingw32 must use the thread-safe MSVCRT library (see the FAQ). You can link
+against the export library libpthread32.a built under Mingw32
+but you must run your application with the version of pthread.dll built
+with MSVC. See the "Known bugs" section above.
+
+Cygwin: (http://sourceware.cygnus.com/cygwin/)
+Cygwin aims to provide a complete POSIX environment on top of Win32, including
+threads. When this is complete, developers using Cygwin will not need
+pthreads-win32. At this time, Cygwin has preliminary support for multithreaded
+development, however, this is not turned on by default. We have not tested
+pthreads-win32 against Cygwin.
+
+Generally:
+For convenience, the following pre-built files are available on the FTP site
+(see Availability above):
+
+ pthread.h - for POSIX 1c threads
+ semaphore.h - for POSIX 1b semaphores
+ sched.h - for POSIX 1b scheduling
+ pthread.dll - built with MSVC cl compiler on NT4.0
+ pthread.lib - built with MSVC cl compiler on NT4.0
+ libpthread32.a - built with Mingw32 on Win98 (use with
+ MSVC pthread.dll for runtime)
+
+These are the only files you need in order to build POSIX threads
+applications for Win32 using either MSVC or Mingw32.
+
+See the FAQ file in the source tree for additional information.
+
+
+Building the library with MSVC
+------------------------------
+
+A simple makefile for building the library with MSVC is available. The
+Makefile by default links the library to MSVCRT.DLL. If your application
+uses another C runtime library like LIBCMT.LIB, please edit the Makefile to
+avoid conflicts between C-libraries.
+
+There is also a batch file "buildlib.bat" which will build the library.
+
+
+Documentation
+-------------
+
+Currently, there is no documentation included in the package apart
+from the copious comments in the source code.
+
+For POSIX Thread API programming, several reference books are
+available:
+
+ Programming with POSIX Threads
+ David R. Butenhof
+ Addison-Wesley (pub)
+
+ Pthreads Programming
+ By Bradford Nichols, Dick Buttlar & Jacqueline Proulx Farrell
+ O'Reilly (pub)
+
+
+Acknowledgements

+implementation contributed by John Bossom <John.Bossom@cognos.com>.
+
+The implementation of condition variables is derived from the work
+of Douglas Schmidt et al
