*
* 1. the long option string
* 2. argument behavior for the option:
* no_argument - no argument permitted
* required_argument - an argument is expected
* optional_argument - an argument is permitted but not required
* 3. this is a pointer to an int which is set to the 4th entry of the
* array if the option is present; or NULL, in which case
* getopt_long() returns the 4th entry
