Well, I take it you mean you can send either the name, the name and host,
the name and host and user, or the name and host and user and password.
If that's the case, you can be ultra-sneaky and do:
my ($name, $host, $user, $pass) = (@_, "", "", "", "");
or even shorter:
my ($name, $host, $user, $pass) = (@_, ("") x 4);
