/* Describe the long-named options requested by the application.
|
|
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
|
|
of `struct option' terminated by an element containing a name which is
|
|
zero.
|
|
|
|
The field `has_arg' is:
|
|
no_argument (or 0) if the option does not take an argument,
|
|
required_argument (or 1) if the option requires an argument,
|
|
optional_argument (or 2) if the option takes an optional argument.
|
|
|
|
If the field `flag' is not NULL, it points to a variable that is set
|
|
to the value given in the field `val' when the option is found, but
|
|
left unchanged if the option is not found.
|
|
|
|
To have a long-named option do something other than set an `int' to
|
|
a compiled-in constant, such as set a value from `optarg', set the
|
|
option's `flag' field to zero and its `val' field to a nonzero
|
|
value (the equivalent single-letter option character, if there is
|
|
one). For long options that have a zero `flag' field, `getopt'
|
|
returns the contents of the `val' field. */

there are no more options. For unrecognized options, or options

missing arguments, `optopt' is set to the option letter, and '?' is

The OPTS string is a list of characters which are recognized option
|
|
letters, optionally followed by colons, specifying that that letter
|
|
takes an argument, to be placed in `optarg'.
|
|
|
|
If a letter in OPTS is followed by two colons, its argument is
|
|
optional. This behavior is specific to the GNU `getopt'.
|
|
|
|
The argument `--' causes premature termination of argument
|
|
scanning, explicitly telling `getopt' that there are no more
|
|
options.
|
|
|
|
If OPTS begins with `--', then non-option arguments are treated as

arguments to the option '\0'. This behavior is specific to the GNU

`getopt'. */
