00013  * Description:
00014  *
00015  * Header file extensions.
00016  *
00017  * The ANSI/ISO C++ standard does not include every routine that is
00018  * legally available in ANSI/ISO C.  Moreover, neither C++ nor C
00019  * include every routine within the standard UNIX specification
00020  * (OpenGroup).  This file provides that extra functionality for
00021  * ANSI/ISO C++ and C code.
00022  *
00023  * Routines available in C are prefixed by c_.
00024  * Routines available in Unix are prefixed by ux_
00025  *
