| 57 If the caller did not specify anything, |
| 58 the default is REQUIRE_ORDER if the environment variable |
| 59 POSIXLY_CORRECT is defined, PERMUTE otherwise. |
| 60 |
| 61 REQUIRE_ORDER means don't recognize them as options; |
| 62 stop option processing when the first non-option is seen. |
| 63 This is what Unix does. |
| 64 This mode of operation is selected by either setting the environment |
| 65 variable POSIXLY_CORRECT, or using `+' as the first character |
| 66 of the list of option characters, or by calling getopt. |
| 67 |
| 68 PERMUTE is the default. We permute the contents of ARGV as we |
| 69 scan, so that eventually all the non-options are at the end. |
| 70 This allows options to be given in any order, even with programs |
| 71 that were not written to expect this. |
| 72 |
| 73 RETURN_IN_ORDER is an option available to programs that were |
| 74 written to expect options and other ARGV-elements in any order |
| 75 and that care about the ordering of the two. We describe each |
| 76 non-option ARGV-element as if it were the argument of an option |
| 77 with character code 1. Using `-' as the first character of the |
| 78 list of option characters selects this mode of operation. |
| 79 |
| 80 The special argument `--' forces an end of option-scanning regardless |
| 81 of the value of `ordering'. In the case of RETURN_IN_ORDER, only |
| 82 `--' can cause `getopt' to return -1 with `optind' != ARGC. */ |
