You need to do this twice, for SOCK_STREAM and SOCK_DGRAM.

I've written an OO-ish socket abstraction, and I used struct
sockaddr_storage as the glue between socket addresses and sockets
(technically, I didn't even have to make the socket address class
abstract, but I think I still did).  There are some safety issues with
this approach, though, and maybe OpenJDK needs to support systems
without struct sockaddr_storage.

Doing away wit socket addresses certainly has some charm, but you really
need them for server sockets, for connectionless sockets, and for
logging purposes.
