| 456 | /* Scan elements of ARGV (whose length is ARGC) for option characters | ||
| 457 | given in OPTSTRING. | ||
| 458 | |||
| 459 | If an element of ARGV starts with '-', and is not exactly "-" or "--", | ||
| 460 | then it is an option element. The characters of this element | ||
| 461 | (aside from the initial '-') are option characters. If `getopt' | ||
| 462 | is called repeatedly, it returns successively each of the option characters | ||
| 463 | from each of the option elements. | ||
| 464 | |||
| 465 | If `getopt' finds another option character, it returns that character, | ||
| 466 | updating `optind' and `nextchar' so that the next call to `getopt' can | ||
| 467 | resume the scan with the following option character or ARGV-element. | ||
| 468 | |||
| 469 | If there are no more option characters, `getopt' returns -1. | ||
| 470 | Then `optind' is the index in ARGV of the first ARGV-element | ||
| 471 | that is not an option. (The ARGV-elements have been permuted | ||
| 472 | so that those that are not options now come last.) | ||
| 473 | |||
| 474 | OPTSTRING is a string containing the legitimate option characters. | ||
| 475 | If an option character is seen that is not listed in OPTSTRING, | ||
| 476 | return '?' after printing an error message. If you set `opterr' to | ||
| 477 | zero, the error message is suppressed but we still return '?'. | ||
| 478 | |||
| 479 | If a char in OPTSTRING is followed by a colon, that means it wants an arg, | ||
| 480 | so the following text in the same ARGV-element, or the text of the following | ||
| 481 | ARGV-element, is returned in `optarg'. Two colons mean an option that | ||
| 482 | wants an optional arg; if there is text in the current ARGV-element, | ||
| 483 | it is returned in `optarg', otherwise `optarg' is set to zero. | ||
| 484 | |||
| 485 | If OPTSTRING starts with `-' or `+', it requests different methods of | ||
| 486 | handling the non-option ARGV-elements. | ||
| 487 | See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. | ||
| 488 | |||
| 489 | Long-named options begin with `--' instead of `-'. | ||
| 490 | Their names may be abbreviated as long as the abbreviation is unique | ||
| 491 | or is an exact match for some defined option. If they have an | ||
| 492 | argument, it follows the option name in the same ARGV-element, separated | ||
| 493 | from the option name by a `=', or else the in next ARGV-element. | ||
| 494 | When `getopt' finds a long-named option, it returns 0 if that option's | ||
| 495 | `flag' field is nonzero, the value of the option's `val' field | ||
| 496 | if the `flag' field is zero. | ||
| 497 | |||
| 498 | The elements of ARGV aren't really const, because we permute them. | ||
| 499 | But we pretend they're const in the prototype to be compatible | ||
| 500 | with other systems. | ||
| 501 | |||
| 502 | LONGOPTS is a vector of `struct option' terminated by an | ||
| 503 | element containing a name which is zero. | ||
| 504 | |||
| 505 | LONGIND returns the index in LONGOPT of the long-named option found. | ||
| 506 | It is only valid when a long-named option has been found by the most | ||
| 507 | recent call. | ||
| 508 | |||
| 509 | If LONG_ONLY is nonzero, '-' as well as '--' can introduce | ||
| 510 | long-named options. */ | ||

| 117 | arguments in ARGV (ARGC of them, minus the program name) for | ||
| 118 | options given in OPTS. | ||
| 119 | |||
| 120 | Return the option character from OPTS just read. Return -1 when | ||
| 121 | there are no more options. For unrecognized options, or options | ||
| 122 | missing arguments, `optopt' is set to the option letter, and '?' is | ||
| 123 | returned. | ||
| 124 | |||
| 125 | The OPTS string is a list of characters which are recognized option | ||
| 126 | letters, optionally followed by colons, specifying that that letter | ||
| 127 | takes an argument, to be placed in `optarg'. | ||
| 128 | |||
| 129 | If a letter in OPTS is followed by two colons, its argument is | ||
| 130 | optional. This behavior is specific to the GNU `getopt'. | ||

| 132 | The argument `--' causes premature termination of argument | ||
| 133 | scanning, explicitly telling `getopt' that there are no more | ||
| 134 | options. | ||
| 135 | |||
| 136 | If OPTS begins with `--', then non-option arguments are treated as | ||
| 137 | arguments to the option '\0'. This behavior is specific to the GNU | ||
