That particular version of the man page evidently - * has no official existence, and my source at AT&T did not send a copy. - * The current SVR2 man page reflects the actual behavor of this getopt. - * However, I am not about to post a copy of anything licensed by AT&T. - */ -#ifdef ANSIPROTO -int strcmp (char *, char *); -char *strchr (char *, char); -#endif +/****************************************************************************** + * + * Module Name: getopt + * $Revision: 1.4 $ + * + *****************************************************************************/ + +/****************************************************************************** + * + * 1.
