509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	166 This is what Unix does.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	167 This mode of operation is selected by either setting the environment
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	168 variable POSIXLY_CORRECT, or using `+' as the first character

509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	178 the ordering of the two. We describe each non-option ARGV-element
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	179 as if it were the argument of an option with character code 1.

509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	461 If an element of ARGV starts with '-', and is not exactly "-" or "--",
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	462 then it is an option element. The characters of this element
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	463 (aside from the initial '-') are option characters. If `getopt'
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	464 is called repeatedly, it returns successively each of the option characters
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	465 from each of the option elements.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	466
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	467 If `getopt' finds another option character, it returns that character,
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	468 updating `optind' and `nextchar' so that the next call to `getopt' can
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	469 resume the scan with the following option character or ARGV-element.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	470
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	471 If there are no more option characters, `getopt' returns -1.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	472 Then `optind' is the index in ARGV of the first ARGV-element
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	473 that is not an option. (The ARGV-elements have been permuted
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	474 so that those that are not options now come last.)

509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	476 OPTSTRING is a string containing the legitimate option characters.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	477 If an option character is seen that is not listed in OPTSTRING,
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	478 return '?' after printing an error message. If you set `opterr' to
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	479 zero, the error message is suppressed but we still return '?'.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	480
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	481 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	482 so the following text in the same ARGV-element, or the text of the following
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	483 ARGV-element, is returned in `optarg'. Two colons mean an option that
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	484 wants an optional arg; if there is text in the current ARGV-element,
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	485 it is returned in `optarg', otherwise `optarg' is set to zero.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	486
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	487 If OPTSTRING starts with `-' or `+', it requests different methods of
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	488 handling the non-option ARGV-elements.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	489 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.

509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	491 Long-named options begin with `--' instead of `-'.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	492 Their names may be abbreviated as long as the abbreviation is unique
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	493 or is an exact match for some defined option. If they have an
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	494 argument, it follows the option name in the same ARGV-element, separated
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	495 from the option name by a `=', or else the in next ARGV-element.
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	496 When `getopt' finds a long-named option, it returns 0 if that option's
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	497 `flag' field is nonzero, the value of the option's `val' field
509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	498 if the `flag' field is zero.

509db1a7b7b8 initial import: leo2moko-r1 Space Falcon <falcon@ivan.Harhan.ORG> parents: diff changeset	500 The elements of ARGV aren't really const, because we permute them.
