Example #1

static int handle_options(int argc, char **argv)
{
	while (true) {
		int c;
		int option_index = 0;

		c = getopt_long (argc, argv, "lhRsairS",
				 long_options, &option_index);
		if (c == -1)
			break;

		switch (c) {
		case 0:

				optarg);
			break;

		case '?':
		case 'h':
			usage(0);
			break;

		default:
			printf ("?? getopt returned character code 0%o ??\n", c);
			usage(-1);
		}
	}
	return 0;
