| 303 | given in OPTSTRING. |
| 304 | |
| 305 | If an element of ARGV starts with '-', and is not exactly "-" or "--", |
| 306 | then it is an option element. The characters of this element |
| 307 | (aside from the initial '-') are option characters. If `getopt' |
| 308 | is called repeatedly, it returns successively each of the option characters |
| 309 | from each of the option elements. |
| 310 | |
| 311 | If `getopt' finds another option character, it returns that character, |
| 312 | updating `optind' and `nextchar' so that the next call to `getopt' can |
| 313 | resume the scan with the following option character or ARGV-element. |
| 314 | |
| 315 | If there are no more option characters, `getopt' returns -1. |
| 316 | Then `optind' is the index in ARGV of the first ARGV-element |
| 317 | that is not an option. (The ARGV-elements have been permuted |
| 318 | so that those that are not options now come last.) |
| 319 | |
| 320 | OPTSTRING is a string containing the legitimate option characters. |
| 321 | If an option character is seen that is not listed in OPTSTRING, |
| 322 | return '?' after printing an error message. If you set `opterr' to |
| 323 | zero, the error message is suppressed but we still return '?'. |
| 324 | |
| 325 | If a char in OPTSTRING is followed by a colon, that means it wants an arg, |
| 326 | so the following text in the same ARGV-element, or the text of the following |
| 327 | ARGV-element, is returned in `optarg'. Two colons mean an option that |
| 328 | wants an optional arg; if there is text in the current ARGV-element, |
| 329 | it is returned in `optarg', otherwise `optarg' is set to zero. |
| 330 | |
| 331 | If OPTSTRING starts with `-' or `+', it requests different methods of |
| 332 | handling the non-option ARGV-elements. |
| 333 | See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. |
| 334 | |
| 335 | Long-named options begin with `--' instead of `-'. |
| 336 | Their names may be abbreviated as long as the abbreviation is unique |
| 337 | or is an exact match for some defined option. If they have an |
| 338 | argument, it follows the option name in the same ARGV-element, separated |
| 339 | from the option name by a `=', or else the in next ARGV-element. |
| 340 | When `getopt' finds a long-named option, it returns 0 if that option's |
| 341 | `flag' field is nonzero, the value of the option's `val' field |
| 342 | if the `flag' field is zero. |
| 343 | |
| 344 | LONGOPTS is a vector of `struct option' terminated by an |
| 345 | element containing a name which is zero. |
| 346 | |
| 347 | LONGIND returns the index in LONGOPT of the long-named option found. |
| 348 | It is only valid when a long-named option has been found by the most |
| 349 | recent call. |
| 350 | |
| 351 | If LONG_ONLY is nonzero, '-' as well as '--' can introduce |
| 352 | long-named options. |
| 353 | |
| 354 | If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT |
