I probably shouldn't keep posting my C questions to this list but I'm
stumped on this command and don't know anybody who can help.
The program below should print the first command line argument but when
I try to compile it I get the errors 'argc' undeclared and 'argv'
undeclared. I've been through the getopt man page dozens of times but I
can't see where it shows how to declare argc and argv. So if they're not
defined in stdlib.h I don't know where they come from.
#include <stdio.h>
#include <stdlib.h>
main()
{
extern char *optarg;
extern int optind;
int ch = 0;
ch = getopt(argc, argv, "abcdefghijklmnopqrstuvwxyz");
printf ("%c\n",ch);
}
At this point I'm so frustrated with this I would be happy with a way of
just getting the command line arguments as a single string and decode
them myself.
Thanks.
