If the caller did not specify anything,

the default is REQUIRE_ORDER if the environment variable

POSIXLY_CORRECT is defined, PERMUTE otherwise.
164
REQUIRE_ORDER means don't recognize them as options;
165
stop option processing when the first non-option is seen.
166
This is what Unix does.
167
This mode of operation is selected by either setting the environment
168
variable POSIXLY_CORRECT, or using `+' as the first character
169
of the list of option characters.
171
PERMUTE is the default. We permute the contents of ARGV as we scan,
172
so that eventually all the non-options are at the end. This allows options
173
to be given in any order, even with programs that were not written to
176
RETURN_IN_ORDER is an option available to programs that were written
177
to expect options and other ARGV-elements in any order and that care about
178
the ordering of the two. We describe each non-option ARGV-element
179
as if it were the argument of an option with character code 1.
180
Using `-' as the first character of the list of option characters
181
selects this mode of operation.
183
The special argument `--' forces an end of option-scanning regardless
184
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
185
`--' can cause `getopt' to return -1 with `optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
461
If an element of ARGV starts with '-', and is not exactly "-" or "--",
462
then it is an option element. The characters of this element
463
(aside from the initial '-') are option characters. If `getopt'
464
is called repeatedly, it returns successively each of the option characters
465
from each of the option elements.
467
If `getopt' finds another option character, it returns that character,
468
updating `optind' and `nextchar' so that the next call to `getopt' can
469
resume the scan with the following option character or ARGV-element.
471
If there are no more option characters, `getopt' returns -1.
472
Then `optind' is the index in ARGV of the first ARGV-element
473
that is not an option. (The ARGV-elements have been permuted
474
so that those that are not options now come last.)
476
OPTSTRING is a string containing the legitimate option characters.
477
If an option character is seen that is not listed in OPTSTRING,
478
return '?' after printing an error message. If you set `opterr' to
479
zero, the error message is suppressed but we still return '?'.
481
If a char in OPTSTRING is followed by a colon, that means it wants an arg,
482
so the following text in the same ARGV-element, or the text of the following
483
ARGV-element, is returned in `optarg'. Two colons mean an option that
484
wants an optional arg; if there is text in the current ARGV-element,
485
it is returned in `optarg', otherwise `optarg' is set to zero.
487
If OPTSTRING starts with `-' or `+', it requests different methods of
488
handling the non-option ARGV-elements.
489
See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
491
Long-named options begin with `--' instead of `-'.
492
Their names may be abbreviated as long as the abbreviation is unique
493
or is an exact match for some defined option. If they have an
494
argument, it follows the option name in the same ARGV-element, separated
495
from the option name by a `=', or else the in next ARGV-element.
496
When `getopt' finds a long-named option, it returns 0 if that option's
497
`flag' field is nonzero, the value of the option's `val' field
498
if the `flag' field is zero.
500
The elements of ARGV aren't really const, because we permute them.
501
But we pretend they're const in the prototype to be compatible
504
LONGOPTS is a vector of `struct option' terminated by an
505
element containing a name which is zero.
507
LONGIND returns the index in LONGOPT of the long-named option found.
