|
|
+ 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 -1 with `optind' != ARGC. */
