|

| 35 |
|
|---|
| 36 | If the caller did not specify anything,
|
|---|
| 37 | the default is REQUIRE_ORDER if the environment variable
|
|---|
| 38 | POSIXLY_CORRECT is defined, PERMUTE otherwise.
|
|---|
| 39 |
|
|---|
| 40 | REQUIRE_ORDER means don't recognize them as options;
|
|---|
| 41 | stop option processing when the first non-option is seen.
|
|---|
| 42 | This is what Unix does.
|
|---|
| 43 | This mode of operation is selected by either setting the environment
|
|---|
| 44 | variable POSIXLY_CORRECT, or using '+' as the first character
|
|---|
| 45 | of the list of option characters, or by calling getopt.
|
|---|
| 46 |
|
|---|
| 47 | PERMUTE is the default. We permute the contents of ARGV as we
|
|---|
| 48 | scan, so that eventually all the non-options are at the end.
|
|---|
| 49 | This allows options to be given in any order, even with programs
|
|---|
| 50 | that were not written to expect this.
|
|---|
| 51 |
|
|---|
| 52 | RETURN_IN_ORDER is an option available to programs that were
|
|---|
| 53 | written to expect options and other ARGV-elements in any order
|
|---|
| 54 | and that care about the ordering of the two. We describe each
|
|---|
| 55 | non-option ARGV-element as if it were the argument of an option
|
|---|
| 56 | with character code 1. Using '-' as the first character of the
|
|---|
| 57 | list of option characters selects this mode of operation.
|
|---|
| 58 |
|
|---|
| 59 | The special argument '--' forces an end of option-scanning regardless
|
|---|
| 60 | of the value of 'ordering'. In the case of RETURN_IN_ORDER, only
|
|---|
| 61 | '--' can cause 'getopt' to return -1 with 'optind' != ARGC. */
