As far as I know, current implementation of getaddrinfo() supports
PF_INET and PF_INET6 only. I'm not 100% sure about the situation of
the latest FreeBSD implemenation, but this is the case at least for
the latest one of KAME's implementation (on which FreeBSD one is
based).
By the way, in my understanding, if getaddrinfo supported PF_UNIX, it
would take the filename as its 1st argument:
getaddrinfo("/tmp/some-socket", NULL, &hints, &res);
