23 /* The option list. Terminated by NAME==NULL. ARG_P that the option
24 requires an argument. INDEX is returned to identify the option. */
33 /* Like getopt() but with simpler semantics.
35 An option has the form ``-<name>''. The special option ``--''
36 denotes the end of the option list. An option can be followed by a
37 separate argument (on a per option basis).
39 On entry OPTIND contains the index of the next element of ARGV that
40 needs parsing. OPTIND is updated to indicate the index of the next
41 argument before mi_getopt() returns.
43 If ARGV[OPTIND] is an option, that options INDEX is returned.
44 OPTARG is set to the options argument or NULL. OPTIND is updated.
46 If ARGV[OPTIND] is not an option, -1 is returned and OPTIND updated
47 to specify the non-option argument. OPTARG is set to NULL.
49 If an unknown option is encountered, mi_getopt() calls
50 ``error("%s: Unknown option %c", prefix, option)'' while
51 mi_getopt_allow_unknown returns -1. */
