46 /* This version of 'getopt' appears to the caller like standard Unix 'getopt'
47 but it behaves differently for the user, since it allows the user
48 to intersperse the options with the other arguments.
50 As 'getopt_long' works, it permutes the elements of ARGV so that,
51 when it is done, all the options precede everything else. Thus
52 all application programs are extended to handle flexible argument order.
54 Using 'getopt' or setting the environment variable POSIXLY_CORRECT
56 Then the behavior is completely standard.
58 GNU application programs can use a third alternative mode in which
59 they can distinguish the relative order of options and other arguments. */

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