Yes, but the port isn't available to the application which opened a
AF_LOCAL connection. If recvfrom returns an AF_INET name, it's rather
tricky to convert it into an AF_LOCAL name for a subsequent sendto call.
[...time passes...]
Or... are you suggesting that recvfrom returns some kind of fake AF_LOCAL
name, which can be converted back to AF_INET by sendto on the fly?
