<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

|
|
implementations</a>.</p>
