| 45 | but it behaves differently for the user, since it allows the user |
| 46 | to intersperse the options with the other arguments. |

| 48 | As 'getopt_long' works, it permutes the elements of ARGV so that, |

| 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 |
