44/* This version of `getopt' appears to the caller like standard Unix `getopt'
45 but it behaves differently for the user, since it allows the user
46 to intersperse the options with the other arguments.
47
48 As `getopt_long' works, it permutes the elements of ARGV so that,
49 when it is done, all the options precede everything else. Thus
50 all application programs are extended to handle flexible argument order.
51
52 Using `getopt' or setting the environment variable POSIXLY_CORRECT
53 disables permutation.
54 Then the behavior is completely standard.
55

289/* Scan elements of ARGV (whose length is ARGC) for option characters
290 given in OPTSTRING.
291
292 If an element of ARGV starts with '-', and is not exactly "-" or "--",
293 then it is an option element. The characters of this element
294 (aside from the initial '-') are option characters. If `getopt'
295 is called repeatedly, it returns successively each of the option characters
296 from each of the option elements.
297
298 If `getopt' finds another option character, it returns that character,
299 updating `optind' and `nextchar' so that the next call to `getopt' can
300 resume the scan with the following option character or ARGV-element.
301
302 If there are no more option characters, `getopt' returns -1.
303 Then `optind' is the index in ARGV of the first ARGV-element
304 that is not an option. (The ARGV-elements have been permuted
305 so that those that are not options now come last.)
306
307 OPTSTRING is a string containing the legitimate option characters.
308 If an option character is seen that is not listed in OPTSTRING,
309 return '?' after printing an error message. If you set `opterr' to
310 zero, the error message is suppressed but we still return '?'.
311
312 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
313 so the following text in the same ARGV-element, or the text of the following
314 ARGV-element, is returned in `optarg'. Two colons mean an option that
315 wants an optional arg; if there is text in the current ARGV-element,
316 it is returned in `optarg', otherwise `optarg' is set to zero.
317
318 If OPTSTRING starts with `-' or `+', it requests different methods of
319 handling the non-option ARGV-elements.
320 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
321
322 Long-named options begin with `--' instead of `-'.
323 Their names may be abbreviated as long as the abbreviation is unique
324 or is an exact match for some defined option. If they have an
325 argument, it follows the option name in the same ARGV-element, separated
326 from the option name by a `=', or else the in next ARGV-element.
327 When `getopt' finds a long-named option, it returns 0 if that option's
328 `flag' field is nonzero, the value of the option's `val' field
329 if the `flag' field is zero.
330
331 The elements of ARGV aren't really const, because we permute them.
332 But we pretend they're const in the prototype to be compatible
333 with other systems.
334
335 LONGOPTS is a vector of `struct option' terminated by an
336 element containing a name which is zero.
337
338 LONGIND returns the index in LONGOPT of the long-named option found.
339 It is only valid when a long-named option has been found by the most
340 recent call.
341
342 If LONG_ONLY is nonzero, '-' as well as '--' can introduce
343 long-named options. */

208 missing arguments, `optopt' is set to the option letter, and '?' is

210
211 The OPTS string is a list of characters which are recognized option
212 letters, optionally followed by colons, specifying that that letter
213 takes an argument, to be placed in `optarg'.
214
215 If a letter in OPTS is followed by two colons, its argument is
216 optional. This behavior is specific to the GNU `getopt'.

218 The argument `--' causes premature termination of argument
219 scanning, explicitly telling `getopt' that there are no more
220 options.
221
222 If OPTS begins with `-', then non-option arguments are treated as
223 arguments to the option '\1'. This behavior is specific to the GNU
224 `getopt'. If OPTS begins with `+', or POSIXLY_CORRECT is set in
225 the environment, then do not permute arguments. */

34
35 If the caller did not specify anything,
36 the default is REQUIRE_ORDER if the environment variable
37 POSIXLY_CORRECT is defined, PERMUTE otherwise.
38
39 REQUIRE_ORDER means don't recognize them as options;
40 stop option processing when the first non-option is seen.
41 This is what Unix does.
42 This mode of operation is selected by either setting the environment
43 variable POSIXLY_CORRECT, or using `+' as the first character
44 of the list of option characters, or by calling getopt.
45
46 PERMUTE is the default. We permute the contents of ARGV as we
47 scan, so that eventually all the non-options are at the end.
48 This allows options to be given in any order, even with programs
49 that were not written to expect this.
50
51 RETURN_IN_ORDER is an option available to programs that were
52 written to expect options and other ARGV-elements in any order
53 and that care about the ordering of the two. We describe each
54 non-option ARGV-element as if it were the argument of an option
55 with character code 1. Using `-' as the first character of the
56 list of option characters selects this mode of operation.
57
58 The special argument `--' forces an end of option-scanning regardless
59 of the value of `ordering'. In the case of RETURN_IN_ORDER, only
60 `--' can cause `getopt' to return -1 with `optind' != ARGC. */
