(The ARGV-elements have been permuted * so that those that are not options now come last.) * * OPTSTRING is a string containing the legitimate option characters. * If an option character is seen that is not listed in OPTSTRING, * return '?' after printing an error message. If you set `custom_opterr' to * zero, the error message is suppressed but we still return '?'. * * If a char in OPTSTRING is followed by a colon, that means it wants an arg, * so the following text in the same ARGV-element, or the text of the following * ARGV-element, is returned in `custom_optarg'. Two colons mean an option that * wants an optional arg; if there is text in the current ARGV-element, * it is returned in `custom_optarg', otherwise `custom_optarg' is set to zero. * * If OPTSTRING starts with `-' or `+', it requests different methods of * handling the non-option ARGV-elements. * See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. * * Long-named options begin with `--' instead of `-'. * Their names may be abbreviated as long as the abbreviation is unique * or is an exact match for some defined option. If they have an * argument, it follows the option name in the same ARGV-element, separated * from the option name by a `=', or else the in next ARGV-element. * When `getopt' finds a long-named option, it returns 0 if that option's * `flag' field is nonzero, the value of the option's `val' field * if the `flag' field is zero. * * The elements of ARGV aren't really const, because we permute them. * But we pretend they're const in the prototype to be compatible * with other systems. * * LONGOPTS is a vector of `struct option' terminated by an * element containing a name which is zero. * * LONGIND returns the index in LONGOPT of the long-named option found. * It is only valid when a long-named option has been found by the most * recent call. * * Return the option character from OPTS just read. Return -1 when there are * no more options. For unrecognized options, or options missing arguments, * `custom_optopt' is set to the option letter, and '?' is returned. * * The OPTS string is a list of characters which are recognized option letters, * optionally followed by colons, specifying that that letter takes an * argument, to be placed in `custom_optarg'. * * If a letter in OPTS is followed by two colons, its argument is optional. * This behavior is specific to the GNU `getopt'. * * The argument `--' causes premature termination of argument scanning, * explicitly telling `getopt' that there are no more options. If OPTS begins * with `--', then non-option arguments are treated as arguments to the option * '\0'.
