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

61 Determines if ARGC/ARGV are a valid set of parameters to satisfy
62 an MI function that is not supposed to recieve any arguments.
64 An MI function that should not recieve arguments can still be
65 passed parameters after the special option '--' such as below.
67 Example: The MI function -exec-run takes no args.
68 However, the client may pass '-exec-run -- -a ...'
71 PREFIX is passed to mi_getopt for an error message.
73 This function Returns 1 if the parameter pair ARGC/ARGV are valid
74 for an MI function that takes no arguments. Otherwise, it returns 0
75 and the appropriate error message is displayed by mi_getopt. */
