If the caller did not specify anything,

the default is REQUIRE_ORDER if the environment variable

POSIXLY_CORRECT is defined, PERMUTE otherwise.
|

|
||||
REQUIRE_ORDER means don't recognize them as options;
|
||||
stop option processing when the first non-option is seen.
|
||||
This is what Unix does.
|
||||
This mode of operation is selected by either setting the environment
|
||||
variable POSIXLY_CORRECT, or using `+' as the first character
|
||||
of the list of option characters.
|
||||
|
||||
PERMUTE is the default. We permute the contents of ARGV as we scan,
|
||||
so that eventually all the non-options are at the end. This allows options
|
||||
to be given in any order, even with programs that were not written to
|
||||
expect this.
|
||||
|
||||
RETURN_IN_ORDER is an option available to programs that were written
|
||||
to expect options and other ARGV-elements in any order and that care about
|
||||
the ordering of the two. We describe each non-option ARGV-element
|
||||
as if it were the argument of an option with character code 1.
|
||||
Using `-' as the first character of the list of option characters
|
||||
selects this mode of operation.
|
||||
|
||||
The special argument `--' forces an end of option-scanning regardless
|
||||
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
|
||||
`--' can cause `getopt' to return EOF with `optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
|

given in OPTSTRING.
|
||||
|
||||
If an element of ARGV starts with '-', and is not exactly "-" or "--",
|
||||
then it is an option element. The characters of this element
|
||||
(aside from the initial '-') are option characters. If `getopt'
|
||||
is called repeatedly, it returns successively each of the option characters
|
||||
from each of the option elements.
|
||||
|
||||
If `getopt' finds another option character, it returns that character,
|
||||
updating `optind' and `nextchar' so that the next call to `getopt' can
|
||||
resume the scan with the following option character or ARGV-element.
|
||||
|
||||
If there are no more option characters, `getopt' returns `EOF'.
|
||||
Then `optind' is the index in ARGV of the first ARGV-element
|
||||
that is not an option. (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 `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 `optarg'. Two colons mean an option that
|
||||
wants an optional arg; if there is text in the current ARGV-element,
|
||||
it is returned in `optarg', otherwise `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.
|
||||
|
||||
If LONG_ONLY is nonzero, '-' as well as '--' can introduce

long-named options. */
