|
|
- the ordering of the two. We describe each non-option ARGV-element |
|
|
- as if it were the argument of an option with character code 1. |
|
|
- Using `-' as the first character of the list of option characters |
|
|
- selects this mode of operation. |
|
|
- |
|
|
- The special argument `--' forces an end of option-scanning regardless |

- If an option character is seen that is not listed in OPTSTRING, |

- zero, the error message is suppressed but we still return '?'. |

- so the following text in the same ARGV-element, or the text of the following |
|
|
- ARGV-element, is returned in `optarg'. Two colons mean an option that |
|

- wants an optional arg; if there is text in the current ARGV-element, |
|
|
- it is returned in `optarg', otherwise `optarg' is set to zero. |
|
|
- |

|
|
- |
|
|
- Long-named options begin with `--' instead of `-'. |
|
|
- Their names may be abbreviated as long as the abbreviation is unique |
|
|
- or is an exact match for some defined option. If they have an |
|
|
- argument, it follows the option name in the same ARGV-element, separated |
|
|
- from the option name by a `=', or else the in next ARGV-element. |
|
|
- When `getopt' finds a long-named option, it returns 0 if that option's |
|
|
- `flag' field is nonzero, the value of the option's `val' field |
|
|
- if the `flag' field is zero. |
|
|
- |
|
|
- The elements of ARGV aren't really const, because we permute them. |
|
|
- But we pretend they're const in the prototype to be compatible |
|
|
- with other systems. |
|
|
- |
|
|
- LONGOPTS is a vector of `struct option' terminated by an |
|
|
- element containing a name which is zero. |
|
|
- |
|
|
- LONGIND returns the index in LONGOPT of the long-named option found. |
|
|
- It is only valid when a long-named option has been found by the most |
|
|
- recent call. |
|
|
- |

|
|
+ Using `-' as the first character of the list of option characters |
|
|
+ selects this mode of operation. |

|
|

|
|
+ from the option name by a `=', or else the in next ARGV-element. |
|
|
+ When `getopt' finds a long-named option, it returns 0 if that option's |
