Oh, you're copying code.  Which means my suggestion of letting the
user specify a length rather than forcing them to NULL-terminate
their array would mean you are no longer matching the version
that you copied from (not necessarily a bad thing).

"less than 1" means "exactly 0", since it is an unsigned param.
