Line 1: {{library}}'''POSIX''' or "Portable Operating System Interface" is ~~the collective name of~~ a ~~family~~standard offor ~~related~~systems ~~standards~~that ~~specified by the~~resemble [[~~IEEE~~Unix]]. toThe ~~define~~current ~~the~~version, ~~application programming interface (~~[~~[API~~http://pubs.opengroup.org/onlinepubs/9699919799/ POSIX.1-2008]]), ~~for~~is ~~software~~a ~~compatible~~project ~~with~~of ~~variants~~both ofthe [[~~UNIX~~IEEE]] and the Open Group. More information ~~found~~is onat [http://en.wikipedia.org/wiki/~~Posix~~POSIX ~~the wiki~~Wikipedia]. * POSIX defines an [[API]] for [[C]] programs, with functions such as <tt>fork()</tt>, <tt>opendir()</tt>, <tt>pthread_create()</tt>, <tt>regcomp()</tt>, <tt>wait()</tt> and <tt>unlink()</tt>. * POSIX also defines commands such as <tt>[[AWK\|awk]]</tt>, <tt>[[bc]]</tt>, <tt>grep</tt>, <tt>ls</tt>, <tt>rm</tt> and <tt>[[UNIX Shell\|sh]]</tt>. The pages in this category have examples marked <nowiki>{{library\|POSIX}}</nowiki>. These examples require some of the POSIX functions; a [[C]] or [[C++]] example that calls <tt>fork()</tt> would be in this category. Some languages, like [[Ada]] or [[Perl]], have a POSIX library.
