Sockets under FreeBSD are just like sockets under any other flavour
of unix (in my experience anyway) - so any book that covers unix sockets
will cover it. I learnt by reading examples like the one you mentioned,
and reading the man pages on each of the calls.
The idea is that you create a socket, then either connect it to another
existing socket (via connect) or wait for a connection to occur
(via bind). You can have different kind of sockets - normally either
a "unix domain" socket or an "internet" socket - depending on how
you create your socket.
Read the man pages and practice :)
