49 | As `getopt' works, it permutes the elements of ARGV so that, | |

99 | If the caller did not specify anything, | |
100 | the default is REQUIRE_ORDER if the environment variable | |
101 | POSIXLY_CORRECT is defined, PERMUTE otherwise. | |
102 | ||
103 | REQUIRE_ORDER means don't recognize them as options; | |
104 | stop option processing when the first non-option is seen. | |
105 | This is what Unix does. | |
106 | This mode of operation is selected by either setting the environment | |
107 | variable POSIXLY_CORRECT, or using `+' as the first character | |
108 | of the list of option characters. | |
109 | ||
110 | PERMUTE is the default. We permute the contents of ARGV as we scan, | |
111 | so that eventually all the non-options are at the end. This allows options | |
112 | to be given in any order, even with programs that were not written to | |
113 | expect this. | |
114 | ||
115 | RETURN_IN_ORDER is an option available to programs that were written | |
116 | to expect options and other ARGV-elements in any order and that care about | |
117 | the ordering of the two. We describe each non-option ARGV-element | |
118 | as if it were the argument of an option with character code 1. | |
119 | Using `-' as the first character of the list of option characters | |
120 | selects this mode of operation. | |
121 | ||
122 | The special argument `--' forces an end of option-scanning regardless | |
123 | of the value of `ordering'. In the case of RETURN_IN_ORDER, only | |
124 | `--' can cause `getopt' to return EOF with `optind' != ARGC. */ | |

207 | /* Scan elements of ARGV (whose length is ARGC) for option characters | |
208 | given in OPTSTRING. | |
209 | ||
210 | If an element of ARGV starts with '-', and is not exactly "-" or "--", | |
211 | then it is an option element. The characters of this element | |
212 | (aside from the initial '-') are option characters. If `getopt' | |
213 | is called repeatedly, it returns successively each of the option characters | |
214 | from each of the option elements. | |
215 | ||
216 | If `getopt' finds another option character, it returns that character, | |
217 | updating `optind' and `nextchar' so that the next call to `getopt' can | |
218 | resume the scan with the following option character or ARGV-element. | |
219 | ||
220 | If there are no more option characters, `getopt' returns `EOF'. | |
221 | Then `optind' is the index in ARGV of the first ARGV-element | |
222 | that is not an option. (The ARGV-elements have been permuted | |
223 | so that those that are not options now come last.) | |
224 | ||
225 | OPTSTRING is a string containing the legitimate option characters. | |
226 | If an option character is seen that is not listed in OPTSTRING, | |
227 | return '?' after printing an error message. If you set `opterr' to | |
228 | zero, the error message is suppressed but we still return '?'. | |
229 | ||
230 | If a char in OPTSTRING is followed by a colon, that means it wants an arg, | |
231 | so the following text in the same ARGV-element, or the text of the following | |
232 | ARGV-element, is returned in `optarg'. Two colons mean an option that | |
233 | wants an optional arg; if there is text in the current ARGV-element, | |
234 | it is returned in `optarg', otherwise `optarg' is set to zero. | |
235 | ||
236 | If OPTSTRING starts with `-' or `+', it requests different methods of | |
237 | handling the non-option ARGV-elements. | |
238 | See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. | |
239 | ||
240 | Long-named options begin with `--' instead of `-'. | |
241 | Their names may be abbreviated as long as the abbreviation is unique | |
242 | or is an exact match for some defined option. If they have an | |
243 | argument, it follows the option name in the same ARGV-element, separated | |
244 | from the option name by a `=', or else the in next ARGV-element. | |
245 | When `getopt' finds a long-named option, it returns 0 if that option's | |
246 | `flag' field is nonzero, the value of the option's `val' field | |
247 | if the `flag' field is zero. | |
248 | ||
249 | The elements of ARGV aren't really const, because we permute them. | |
250 | But we pretend they're const in the prototype to be compatible | |
251 | with other systems. | |
252 | ||
253 | LONGOPTS is a vector of `struct option' terminated by an | |
254 | element containing a name which is zero. | |
255 | ||
256 | LONGIND returns the index in LONGOPT of the long-named option found. | |
257 | It is only valid when a long-named option has been found by the most | |
258 | recent call. | |
259 | ||
