The general questions mailing list (this one - freebsd-questions)
is probably appropriate. In worst case, address the freebsd-hackers
list. For more information see:

Without further investigation, I'd suggest to check the
section EXAMPLES in "man 3 getopt_long". If I remember
correctly, you define optional_argument for the flag and
check if optarg is a valid string (or NULL)...
