pthreads-w32 seeks to provide a freely available and high-quality implementation of pthreads for Windows. Pthreads is an API for writing multithreaded applications following the POSIX standard. The mingw32-pthreads-w32 package provides the documentation for the pthreads-w32 library, as well as the related development files. The associated mingw32-libpthread package provides the runtime library. NOTE: The 2.9.1 release delivers this library as part of the pthreads-w32-2.9.1-1-mingw32-dll.tar.lzma file. This DLL file is a dependency for gcc-core-4.8.1 and will be installed as such when using mingw-get. pthreads-w32 seeks to provide a freely available and high-quality implementation of pthreads for Windows. Pthreads is an API for writing multithreaded applications following the POSIX standard. There are two mingw32 versions of the pthread-w32 runtime library: the standard one, provided by this package, is called libpthreadgc but may also be referred to as 'libpthread'. The non-standard one uses C++ exception handling, and is called libpthreadgce. (Note that the standard library may be used successfully with C++ code; indeed, on most *nix platorms the system pthreads implementation follows the behavior of mingw32-libpthreadgc, and NOT the behavior of the 'GCE' version). We recommend that most users rely on mingw32-libpthreadgc ('GC') and not mingw32-libpthreadgce ('GCE'). The mingw32-libpthreadgc and mingw32-libpthreadgce packages provide the two runtime libraries (most people need not install the 'GCE' one). The associated mingw32-pthreads-w32 package provides the documentation for the pthreads-w32 library, as well as the related development files. The mingw32-libquserex package provides optional support for enhanced standards conformance of the GCE runtime. mingw32-libpthreadgc is a required component of the MinGW Compiler Suite.

The mingw32-libquserex package provides optional support for enhanced standards conformance of the GCE runtime. NOTE: The 2.9.1 and later releases do not deliver this library. This decision was based on the number of downloads for the library and the fact that it is experimental. pthreads-w32 seeks to provide a freely available and high-quality implementation of pthreads for Windows. Pthreads is an API for writing multithreaded applications following the POSIX standard. libquserex is an optional library to enable enhanced standards conformance of the non-standard mingw32-libpthreadgce ('GCE') runtime. It provides access to a a kernel mode driver, AlertDrv.sys, which if installed allows ordinary users to exploit the Win32 QueueUserAPCEx function call. There are two mingw32 versions of the pthread-w32 runtime library: the non-standard one provided by mingw32-libpthreadgce ('GCE') uses C++ exceptions, and for full POSIX conformance needs a kernel mode driver installed. The standard runtime, mingw32-libpthreadgc ('GC') does not require that driver for full standards conformance, and may be used with C++ code; we recommend that most users rely on mingw32-libpthreadgc ('GC') and not mingw32-libpthreadgce ('GCE'). However, for those that wish to experiment with the non-standard ('GCE') runtime, this optional helper library may also be of use -- provided the kernel mode driver, available from mingw.org, is also installed. Note that the kernel mode driver can not currently be installed on W7 (64bit) or Windows Server 2008R2 (64bit) because those operating systems require kernel mode drivers to be digitally signed, so this mingw32-libquserex package is rather useless on those platforms. The kernel mode driver is available at mingw.org or mirror site, packaged as an InnoSetup installer executable called QueueUserAPCEx-installer.exe. pthreads-w32 seeks to provide a freely available and high-quality implementation of pthreads for Windows. Pthreads is an API for writing multithreaded applications following the POSIX standard. The mingw32-libpthread-old package provides the MinGW pthreads-w32 runtime dll associated with MinGW GCC 4.5.2 and older. Due to an unfortunate naming choice, upgrading to newer GCC will also install the newer, renamed pthreads-w32 DLLs, removing the old DLL. While the may not affect the new GCC, threaded applications compiled using the older compiler will break, as they will miss this runtime library. Therefore, the old runtime library is provided here using a new package name: mingw32-libpthread-old, so that it can be (re)installed parallel to the new pthreads-w32 runtime libraries.
