LXXVII. POSIX functions
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.
