GETOPT-variables

- some variables used in the getopt function

SYNOPSIS

char *optarg Pointer set to the start of the option argument upon return from the getopt function.
int optind Contains the argv index of the next argument to be processed.
int opterr If set to 0, error messages will be disabled.

DESCRIPTION

These variables are used in communicating with the getopt function. This function is only used in MS-DOS compilations, since this operating system lacks a program parameter parsing routine. The routine behaves more or less like the standard UNIX getopt function (from unistd.h).
