25 | /* Like getopt() but with simpler semantics. | |
26 | ||
27 | An option has the form ``-<name>''. The special option ``--'' | |
28 | denotes the end of the option list. An option can be followed by a | |
29 | separate argument (on a per option basis). | |
30 | ||
31 | On entry OPTIND contains the index of the next element of ARGV that | |
32 | needs parsing. OPTIND is updated to indicate the index of the next | |
33 | argument before mi_getopt() returns. | |
34 | ||
35 | If ARGV[OPTIND] is an option, that options INDEX is returned. | |
36 | OPTARG is set to the options argument or NULL. OPTIND is updated. | |
37 | ||
38 | If ARGV[OPTIND] is not an option, -1 is returned and OPTIND updated | |
39 | to specify the non-option argument. OPTARG is set to NULL. | |
40 | ||
41 | mi_getopt() calls ``error("%s: Unknown option %c", prefix, | |
42 | option)'' if an unknown option is encountered. */ | |
