127 If the caller did not specify anything,

129 POSIXLY_CORRECT is defined, PERMUTE otherwise.
130
131 REQUIRE_ORDER means don't recognize them as options;
132 stop option processing when the first non-option is seen.
133 This is what Unix does.
134 This mode of operation is selected by either setting the environment
135 variable POSIXLY_CORRECT, or using `+' as the first character
136 of the list of option characters.
137
138 PERMUTE is the default. We permute the contents of ARGV as we scan,
139 so that eventually all the non-options are at the end. This allows options
140 to be given in any order, even with programs that were not written to
141 expect this.
142
143 RETURN_IN_ORDER is an option available to programs that were written
144 to expect options and other ARGV-elements in any order and that care about
145 the ordering of the two. We describe each non-option ARGV-element
146 as if it were the argument of an option with character code 1.
147 Using `-' as the first character of the list of option characters
148 selects this mode of operation.
149
150 The special argument `--' forces an end of option-scanning regardless
151 of the value of `ordering'. In the case of RETURN_IN_ORDER, only
152 `--' can cause `getopt' to return EOF with `optind' != ARGC. */

310 given in OPTSTRING.
311
312 If an element of ARGV starts with '-', and is not exactly "-" or "--",
313 then it is an option element. The characters of this element
314 (aside from the initial '-') are option characters. If `getopt'
315 is called repeatedly, it returns successively each of the option characters
316 from each of the option elements.
317
318 If `getopt' finds another option character, it returns that character,
319 updating `optind' and `nextchar' so that the next call to `getopt' can
320 resume the scan with the following option character or ARGV-element.
321
322 If there are no more option characters, `getopt' returns `EOF'.
323 Then `optind' is the index in ARGV of the first ARGV-element
324 that is not an option. (The ARGV-elements have been permuted
325 so that those that are not options now come last.)
326
327 OPTSTRING is a string containing the legitimate option characters.
328 If an option character is seen that is not listed in OPTSTRING,
329 return '?' after printing an error message. If you set `opterr' to
330 zero, the error message is suppressed but we still return '?'.
331
332 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
333 so the following text in the same ARGV-element, or the text of the following
334 ARGV-element, is returned in `optarg'. Two colons mean an option that
335 wants an optional arg; if there is text in the current ARGV-element,
336 it is returned in `optarg', otherwise `optarg' is set to zero.
337
338 If OPTSTRING starts with `-' or `+', it requests different methods of
339 handling the non-option ARGV-elements.
340 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
341
342 Long-named options begin with `--' instead of `-'.
343 Their names may be abbreviated as long as the abbreviation is unique
344 or is an exact match for some defined option. If they have an
345 argument, it follows the option name in the same ARGV-element, separated
346 from the option name by a `=', or else the in next ARGV-element.
347 When `getopt' finds a long-named option, it returns 0 if that option's
348 `flag' field is nonzero, the value of the option's `val' field
349 if the `flag' field is zero.
350
351 The elements of ARGV aren't really const, because we permute them.
352 But we pretend they're const in the prototype to be compatible
353 with other systems.
354
355 LONGOPTS is a vector of `struct option' terminated by an
356 element containing a name which is zero.
357
358 LONGIND returns the index in LONGOPT of the long-named option found.
359 It is only valid when a long-named option has been found by the most
360 recent call.
361
362 If LONG_ONLY is nonzero, '-' as well as '--' can introduce
363 long-named options. */
