caf8a9b2 | 44 | /* This version of 'getopt' appears to the caller like standard Unix 'getopt' |
e275c824 PE |
45 | but it behaves differently for the user, since it allows the user |
46 | to intersperse the options with the other arguments. | |
47 | ||
caf8a9b2 | 48 | As 'getopt_long' works, it permutes the elements of ARGV so that, |
e275c824 PE |
49 | when it is done, all the options precede everything else. Thus |
50 | all application programs are extended to handle flexible argument order. | |
51 | ||
caf8a9b2 | 52 | Using 'getopt' or setting the environment variable POSIXLY_CORRECT |
e275c824 PE |
53 | disables permutation. |
54 | Then the behavior is completely standard. | |
55 | ||
56 | GNU application programs can use a third alternative mode in which | |
57 | they can distinguish the relative order of options and other arguments. */ | |

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 | |
caf8a9b2 | 294 | (aside from the initial '-') are option characters. If 'getopt' |
e275c824 PE |
295 | is called repeatedly, it returns successively each of the option characters |
296 | from each of the option elements. | |
297 | ||
caf8a9b2 PE |
298 | If 'getopt' finds another option character, it returns that character, |
299 | updating 'optind' and 'nextchar' so that the next call to 'getopt' can | |
e275c824 PE |
300 | resume the scan with the following option character or ARGV-element. |
301 | ||
caf8a9b2 PE |
302 | If there are no more option characters, 'getopt' returns -1. |
303 | Then 'optind' is the index in ARGV of the first ARGV-element | |
e275c824 PE |
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, | |
caf8a9b2 | 309 | return '?' after printing an error message. If you set 'opterr' to |
e275c824 PE |
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 | |
caf8a9b2 | 314 | ARGV-element, is returned in 'optarg'. Two colons mean an option that |
e275c824 | 315 | wants an optional arg; if there is text in the current ARGV-element, |
caf8a9b2 | 316 | it is returned in 'optarg', otherwise 'optarg' is set to zero. |
e275c824 | 317 | |
caf8a9b2 | 318 | If OPTSTRING starts with '-' or '+', it requests different methods of |
e275c824 PE |
319 | handling the non-option ARGV-elements. |
320 | See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. | |
321 | ||
caf8a9b2 | 322 | Long-named options begin with '--' instead of '-'. |
e275c824 PE |
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 | |
caf8a9b2 PE |
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. | |
e275c824 PE |
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 | ||
caf8a9b2 | 335 | LONGOPTS is a vector of 'struct option' terminated by an |
e275c824 PE |
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. | |
