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