<h2>What are Pthreads?</h2>
<p>Portable Operating System Interface for Computer Environments (POSIX) is an
interface standard governed by the IEEE and based on UNIX. POSIX is an evolving
family of standards that describe a wide spectrum of operating system
components ranging from C language and shell interfaces to system
administration.</p>
<p>The Pthread interfaces described in this section are based on a subset of
the application programming interfaces (APIs) defined in the POSIX standard
(ANSI/IEEE Standard 1003.1, 1996 Edition OR ISO/IEC 9945-1: 1996) and the
Single UNIX Specification, Version 2, 1997. The implementation of these APIs is
not compliant with these standards. However, the implementation does attempt to
duplicate the portable nature of the interfaces defined by the standards.
Differences between Pthreads in i5/OS and other thread types are described in
<a href="diffs.htm">i5/OS Pthreads versus other threads
implementations</a>.</p>
