You could use gethostbyaddr(3), but those traditional functions have
been replaced with more flexible versions such as getnameinfo(3) on
newer systems. There's a good introduction to modern sockets
programming at http://people.redhat.com/drepper/userapi-ipv6.html
Ups - yes that's what I ment in my mail.
I wrote getaddrinfo, which is the other direction...
