I think that C programmers shouldn't have much trouble either way:
(address-family inet) and *af-inet* both look pretty close to AF_INET.
The macros have the advantage that it's possible to check at compile
time that the value being passed in is valid, which is not possible with
the variables.

You can use bound UDP sockets with this API, but not unbound ones:
for those you need access to sendto() and recvfrom().  See
