56/* This implementation of 'getopt' has three modes for handling
57 options interspersed with non-option arguments. It can stop
58 scanning for options at the first non-option argument encountered,
59 as POSIX specifies. It can continue scanning for options after the
60 first non-option argument, but permute 'argv' as it goes so that,
61 after 'getopt' is done, all the options precede all the non-option
62 arguments and 'optind' points to the first non-option argument.
63 Or, it can report non-option arguments as if they were arguments to
64 the option character '\x01'.
65
66 The default behavior of 'getopt_long' is to permute the argument list.
67 When this implementation is used standalone, the default behavior of
68 'getopt' is to stop at the first non-option argument, but when it is
69 used as part of GNU libc it also permutes the argument list. In both
70 cases, setting the environment variable POSIXLY_CORRECT to any value
71 disables permutation.
72
73 If the first character of the OPTSTRING argument to 'getopt' or
74 'getopt_long' is '+', both functions will stop at the first
75 non-option argument. If it is '-', both functions will report
76 non-option arguments as arguments to the option character '\x01'. */

412 given in OPTSTRING.
413
414 If an element of ARGV starts with '-', and is not exactly "-" or "--",
415 then it is an option element. The characters of this element
416 (aside from the initial '-') are option characters. If 'getopt'
417 is called repeatedly, it returns successively each of the option characters
418 from each of the option elements.
419
420 If 'getopt' finds another option character, it returns that character,
421 updating 'optind' and 'nextchar' so that the next call to 'getopt' can
422 resume the scan with the following option character or ARGV-element.
423
424 If there are no more option characters, 'getopt' returns -1.
425 Then 'optind' is the index in ARGV of the first ARGV-element
426 that is not an option. (The ARGV-elements have been permuted
427 so that those that are not options now come last.)
428
429 OPTSTRING is a string containing the legitimate option characters.
430 If an option character is seen that is not listed in OPTSTRING,
431 return '?' after printing an error message. If you set 'opterr' to
432 zero, the error message is suppressed but we still return '?'.
433
434 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
435 so the following text in the same ARGV-element, or the text of the following
436 ARGV-element, is returned in 'optarg'. Two colons mean an option that
437 wants an optional arg; if there is text in the current ARGV-element,
438 it is returned in 'optarg', otherwise 'optarg' is set to zero.
439
440 If OPTSTRING starts with '-' or '+', it requests different methods of
441 handling the non-option ARGV-elements.
442 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
443
444 Long-named options begin with '--' instead of '-'.
445 Their names may be abbreviated as long as the abbreviation is unique
446 or is an exact match for some defined option. If they have an
447 argument, it follows the option name in the same ARGV-element, separated
448 from the option name by a '=', or else the in next ARGV-element.
449 When 'getopt' finds a long-named option, it returns 0 if that option's
450 'flag' field is nonzero, the value of the option's 'val' field
451 if the 'flag' field is zero.
452
453 The elements of ARGV aren't really const, because we permute them.
454 But we pretend they're const in the prototype to be compatible
455 with other systems.
456
457 LONGOPTS is a vector of 'struct option' terminated by an
458 element containing a name which is zero.
459
460 LONGIND returns the index in LONGOPT of the long-named option found.
461 It is only valid when a long-named option has been found by the most
462 recent call.
463
464 If LONG_ONLY is nonzero, '-' as well as '--' can introduce
465 long-named options. */
