178 This mode of operation is selected by either setting the environment
179 variable POSIXLY_CORRECT, or using `+' as the first character
180 of the list of option characters.
182 PERMUTE is the default. We permute the contents of ARGV as we scan,

190 as if it were the argument of an option with character code 1.

192 selects this mode of operation.

472 If an element of ARGV starts with '-', and is not exactly "-" or "--",
473 then it is an option element. The characters of this element
474 (aside from the initial '-') are option characters. If `getopt'
475 is called repeatedly, it returns successively each of the option characters
476 from each of the option elements.
478 If `getopt' finds another option character, it returns that character,
479 updating `optind' and `nextchar' so that the next call to `getopt' can
480 resume the scan with the following option character or ARGV-element.
482 If there are no more option characters, `getopt' returns -1.
483 Then `optind' is the index in ARGV of the first ARGV-element
484 that is not an option. (The ARGV-elements have been permuted
485 so that those that are not options now come last.)
487 OPTSTRING is a string containing the legitimate option characters.
488 If an option character is seen that is not listed in OPTSTRING,
489 return '?' after printing an error message. If you set `opterr' to
490 zero, the error message is suppressed but we still return '?'.
492 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
493 so the following text in the same ARGV-element, or the text of the following
494 ARGV-element, is returned in `optarg'. Two colons mean an option that
495 wants an optional arg; if there is text in the current ARGV-element,
496 it is returned in `optarg', otherwise `optarg' is set to zero.
498 If OPTSTRING starts with `-' or `+', it requests different methods of
499 handling the non-option ARGV-elements.
500 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
502 Long-named options begin with `--' instead of `-'.
503 Their names may be abbreviated as long as the abbreviation is unique
504 or is an exact match for some defined option. If they have an
505 argument, it follows the option name in the same ARGV-element, separated
506 from the option name by a `=', or else the in next ARGV-element.
507 When `getopt' finds a long-named option, it returns 0 if that option's
508 `flag' field is nonzero, the value of the option's `val' field
509 if the `flag' field is zero.
511 The elements of ARGV aren't really const, because we permute them.
512 But we pretend they're const in the prototype to be compatible
515 LONGOPTS is a vector of `struct option' terminated by an
516 element containing a name which is zero.
518 LONGIND returns the index in LONGOPT of the long-named option found.
