/* 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. */
