>&#13;    This module contains an interface to those functions defined in the
    IEEE 1003.1 (POSIX.1) standards document which are not accessible
    through other means. POSIX.1 for example defined the open(), read(),
    write() and close() functions, too, which traditionally have been
    part of PHP 3 for a long time. Some more system specific functions
    have not been available before, though, and this module tries to
    remedy this by providing easy access to these functions.
