How does one send/receive multicast packets?

I'm assuming that in order to send, one uses something like:
dial("udp!224.100.100.100!64470", nil, nil, nil)

However, I'm not quite sure about receiving.
I see an "addmulti" in ip(3) but I don't quite understand the comment
and I couldn't penetrate the source.

Thanks.

Justin
