- 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. */
