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