51 but it behaves differently for the user, since it allows the user
52 to intersperse the options with the other arguments.
54 As `getopt_long' works, it permutes the elements of ARGV so that,
55 when it is done, all the options precede everything else. Thus
56 all application programs are extended to handle flexible argument order.
58 Using `getopt' or setting the environment variable POSIXLY_CORRECT

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