Editing Pthreads (section)

== POSIX Threads for Windows ==
Windows does not support the pthreads standard natively, therefore the Pthreads4w project seeks to provide a portable and open-source [[Wrapper library|wrapper]] implementation. It can also be used to port [[Unix]] software (which uses pthreads) with little or no modification to the Windows platform.<ref>{{cite web |url=http://world.std.com/~jmhart/opensource.htm |title=Experiments with the Open Source Pthreads Library and Some Comments |last=Hart |first=Johnson M. |date=2004-11-21 |access-date=2010-08-29 |url-status=dead |archive-url=https://web.archive.org/web/20100830235615/http://world.std.com/~jmhart/opensource.htm |archive-date=2010-08-30 }}</ref> Pthreads4w version 3.0.0<ref>[https://sourceforge.net/projects/pthreads4w/files/ File: pthreads4w-code-v3.0.0.zip – Source for pthreads4w v3.0.0]</ref> or later, released under the Apache Public License v2.0, is compatible with 64-bit or 32-bit Windows systems.

The [[Mingw-w64]] project also contains a wrapper implementation of 'pthreads, '''winpthreads''', which tries to use more native system calls than the Pthreads4w project.<ref>see http://locklessinc.com/articles/pthreads_on_windows which is where it was originally derived from</ref>

[[Interix]] environment subsystem available in the [[Windows Services for UNIX|Windows Services for UNIX/Subsystem for UNIX-based Applications]] package provides a native port of the pthreads API, i.e. not mapped on Win32 API but built directly on the operating system [[syscall]] interface.<ref>{{cite web |url=https://technet.microsoft.com/en-us/library/bb496994.aspx |title=Chapter 1: Introduction to Windows Services for UNIX 3.5|date=5 December 2007 }}</ref>
