-Pthreads-win32 is free software, distributed under the GNU Lesser

-
-What is it?
------------
-
-Pthreads-win32 is an Open Source Software 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. The library also supports
-some of the functionality of the Open Group's Single Unix
-specification, version 2, namely mutex types.
-
-See the file "ANNOUNCE" for more information including standards
-conformance details and list of supported routines.

-
-Which of the several dll versions to use?
------------------------------------------
-or,
----
-What are all these pthread*.dll and pthread*.lib files?
--------------------------------------------------------
-
-Simply, you only use one of them, but you need to choose carefully.
-
-The most important choice you need to make is whether to use a
-version that uses exceptions internally, or not (there are versions
-of the library that use exceptions as part of the thread
-cancelation and exit implementation, and one that uses
-setjmp/longjmp instead).
-
-There is some contension amongst POSIX threads experts as
-to how POSIX threads cancelation and exit should work
-with languages that include exceptions and handlers, e.g.
-C++ and even C (Microsoft's Structured Exceptions).
-
-The issue is: should cancelation of a thread in, say,
-a C++ application cause object destructors and C++ exception
-handlers to be invoked as the stack unwinds during thread
-exit, or not?
-
-There seems to be more opinion in favour of using the
-standard C version of the library (no EH) with C++ applications
-since this appears to be the assumption commercial pthreads
-implementations make. Therefore, if you use an EH version
-of pthreads-win32 then you may be under the illusion that
-your application will be portable, when in fact it is likely to
-behave very differently linked with other pthreads libraries.
-
-Now you may be asking: why have you kept the EH versions of
-the library?
-
-There are a couple of reasons:
-- there is division amongst the experts and so the code may
- be needed in the future. (Yes, it's in the repository and we
- can get it out anytime in the future, but ...)
-- pthreads-win32 is one of the few implementations, and possibly
- the only freely available one, that has EH versions. It may be
- useful to people who want to play with or study application
- behaviour under these conditions.
-
-
-Library naming
---------------
-
-Because the library is being built using various exception
-handling schemes and compilers - and because the library
-may not work reliably if these are mixed in an application,
-each different version of the library has it's own name.
-
-Note 1: the incompatibility is really between EH implementations
-of the different compilers. It should be possible to use the
-standard C version from either compiler with C++ applications
-built with a different compiler. If you use an EH version of
-the library, then you must use the same compiler for the
-application. This is another complication and dependency that
-can be avoided by using only the standard C library version.
-
-Note 2: if you use a standard C pthread*.dll with a C++
-application, then any functions that you define that are
-intended to be called via pthread_cleanup_push() must be
-__cdecl.
-
-Note 3: the intention is to also name either the VC or GC
-version (it should be arbitrary) as pthread.dll, including
-pthread.lib and libpthread.a as appropriate.
-
-In general:
- pthread[VG]{SE,CE,C}.dll
- pthread[VG]{SE,CE,C}.lib
-
-where:
- [VG] indicates the compiler
- V - MS VC
- G - GNU C
-
- {SE,CE,C} indicates the exception handling scheme
- SE - Structured EH
- CE - C++ EH
- C - no exceptions - uses setjmp/longjmp
-
-For example:
- pthreadVSE.dll (MSVC/SEH)
- pthreadGCE.dll (GNUC/C++ EH)
- pthreadGC.dll (GNUC/not dependent on exceptions)
-
-The GNU library archive file names have changed to:
-
- libpthreadGCE.a
- libpthreadGC.a
-
-
-Other name changes
-------------------
-
-All snapshots prior to and including snapshot 2000-08-13
-used "_pthread_" as the prefix to library internal
-functions, and "_PTHREAD_" to many library internal
-macros. These have now been changed to "ptw32_" and "PTW32_"
-respectively so as to not conflict with the ANSI standard's
-reservation of identifiers beginning with "_" and "__" for
-use by compiler implementations only.
-
-If you have written any applications and you are linking
-statically with the pthreads-win32 library then you may have
-included a call to _pthread_processInitialize. You will
-now have to change that to ptw32_processInitialize.
-
-
-A note on Cleanup code default style
-------------------------------------
-
-Previously, if not defined, the cleanup style was determined automatically
-from the compiler used, and one of the following was defined accordingly:
-
- __CLEANUP_SEH MSVC only
- __CLEANUP_CXX C++, including MSVC++, GNU G++
- __CLEANUP_C C, including GNU GCC, not MSVC
-
-These defines determine the style of cleanup (see pthread.h) and,
-most importantly, the way that cancelation and thread exit (via
-pthread_exit) is performed (see the routine ptw32_throw() in private.c).
-
-In short, the exceptions versions of the library throw an exception
-when a thread is canceled or exits (via pthread_exit()), which is
-caught by a handler in the thread startup routine, so that the
-the correct stack unwinding occurs regardless of where the thread
-is when it's canceled or exits via pthread_exit().
-
-In this snapshot, unless the build explicitly defines (e.g. via a
-compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then
-the build NOW always defaults to __CLEANUP_C style cleanup. This style
-uses setjmp/longjmp in the cancelation and pthread_exit implementations,
-and therefore won't do stack unwinding even when linked to applications
-that have it (e.g. C++ apps). This is for consistency with most/all
-commercial Unix POSIX threads implementations.
-
-Although it was not clearly documented before, it is still necessary to
-build your application using the same __CLEANUP_* define as was
-used for the version of the library that you link with, so that the
-correct parts of pthread.h are included. That is, the possible
-defines require the following library versions:
-
- __CLEANUP_SEH pthreadVSE.dll
- __CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll
- __CLEANUP_C pthreadVC.dll or pthreadGC.dll
-
-THE POINT OF ALL THIS IS: if you have not been defining one of these
-explicitly, then the defaults as described at the top of this
-section were being used.
-
-THIS NOW CHANGES, as has been explained above, but to try to make this
-clearer here's an example:
-
-If you were building your application with MSVC++ i.e. using C++
-exceptions (rather than SEH) and not explicitly defining one of
-__CLEANUP_*, then __CLEANUP_C++ was defined for you in pthread.h.
-You should have been linking with pthreadVCE.dll, which does
-stack unwinding.
-
-If you now build your application as you had before, pthread.h will now
-set __CLEANUP_C as the default style, and you will need to link
-with pthreadVC.dll. Stack unwinding will now NOT occur when a thread
-is canceled, or the thread calls pthread_exit().
-
-Your application will now most likely behave differently to previous
-versions, and in non-obvious ways. Most likely is that locally
-instantiated objects may not be destroyed or cleaned up after a thread
-is canceled.
-
-If you want the same behaviour as before, then you must now define
-__CLEANUP_C++ explicitly using a compiler option and link with
-pthreadVCE.dll as you did before.
-
-
-WHY ARE WE MAKING THE DEFAULT STYLE LESS EXCEPTION-FRIENDLY?
-Because no commercial Unix POSIX threads implementation allows you to
-choose to have stack unwinding. Therefore, providing it in pthread-win32
-as a default is dangerous. We still provide the choice but unless
-you consciously choose to do otherwise, your pthreads applications will
-now run or crash in similar ways irrespective of the threads platform
-you use. Or at least this is the hope.
-
-
-
-Building under VC++ using C++ EH, Structured EH, or just C
-----------------------------------------------------------
-
-From the source directory run one of the following:
-
-nmake clean VCE (builds the VC++ C++ EH version pthreadVCE.dll)
-
-or:
-
-nmake clean VSE (builds the VC++ structured EH version pthreadVSE.dll)
-
-or:
-
-nmake clean VC (builds the VC setjmp/longjmp version of pthreadVC.dll)
-
-You can run the testsuite by changing to the "tests" directory and
-running the target corresponding to the DLL version you built:
-
-nmake clean VCE
-
-or:
-
-nmake clean VSE
-
-or:
-
-nmake clean VC
-
-or:
-
-nmake clean VCX (tests the VC version of the library with C++ (EH)
- applications)
-
-
-Building under Mingw32
-----------------------
-
-The dll can be built with Mingw32 gcc-2.95.2-1 after you've
-made the changes to Mingw32 desribed in Question 6 of the FAQ.
-
-From the source directory, run
-
-make clean GCE
-
-or:
-
-make clean GC
-
-You can run the testsuite by changing to the "tests" directory and
-running
-
-make clean GCE
-
-or:
-
-make clean GC
-
-or:
-
-make clean GCX (tests the GC version of the library with C++ (EH)
- applications)
-
-
-Building the library under Cygwin
----------------------------------
-
-Not tested by me although I think some people have done this.
-Not sure how successfully though.
-
-Cygwin is implementing it's own POSIX threads routines and these
-will be the ones to use if you develop using Cygwin.
-
-
-Ready to run binaries
----------------------
-
-For convenience, the following ready-to-run files can be downloaded
-from the FTP site (see under "Availability" below):
-
- pthread.h
- semaphore.h
- sched.h
- pthread.def
- pthreadVCE.dll - built with MSVC++ compiler using C++ EH
- pthreadVCE.lib
- pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
- pthreadVC.lib
- pthreadVSE.dll - built with MSVC compiler using SEH
- pthreadVSE.lib
- pthreadGCE.dll - built with Mingw32 G++
- pthreadGCE.a - derived from pthreadGCE.dll
- pthreadGC.dll - built with Mingw32 GCC
- pthreadGC.a - derived from pthreadGC.dll
- gcc.dll - needed to build and run applications that use
- pthreadGCE.dll.
-
-
-Building applications with the library
---------------------------------------
-
-Use the appropriate DLL and LIB files to match the exception handing
-that you use in your application, or specifically, in your POSIX
-threads. Don't mix them or neither thread cancelation nor
-pthread_exit() will work reliably if at all.
-
-If in doubt use the C (no-exceptions) versions of the library.
-
-
-Building applications with GNU compilers
-----------------------------------------
-
-If you're using pthreadGCE.dll:
-
-Use gcc-2.95.2-1 or later modified as per pthreads-win32 FAQ question 11.
-
-With the three header files, pthreadGCE.dll, gcc.dll and libpthreadGCE.a
-in the same directory as your application myapp.c, you could compile,
-link and run myapp.c under Mingw32 as follows:
-
- gcc -x c++ -o myapp.exe myapp.c -I. -L. -lpthreadGCE
- myapp
-
-Or put pthreadGCE.dll and gcc.dll in an appropriate directory in
-your PATH, put libpthreadGCE.a in MINGW_ROOT\i386-mingw32\lib, and
-put the three header files in MINGW_ROOT\i386-mingw32\include,
-then use:
-
- gcc -x c++ -o myapp.exe myapp.c -lpthreadGCE
- myapp
-
-If you're using pthreadGC.dll:
-
-With the three header files, pthreadGC.dll and libpthreadGC.a in the
-same directory as your application myapp.c, you could compile, link
-and run myapp.c under Mingw32 as follows:
-
- gcc -o myapp.exe myapp.c -I. -L. -lpthreadGC
- myapp
-
-Or put pthreadGC.dll in an appropriate directory in your PATH,
-put libpthreadGC.a in MINGW_ROOT\i386-mingw32\lib, and
-put the three header files in MINGW_ROOT\i386-mingw32\include,
-then use:
-
- gcc -o myapp.exe myapp.c -lpthreadGC
- myapp
