Thanks a lot, this actually fixed my problem.
In case it may help someone else: I also need to make the socket
reusable by
setsockopt(tcp_broadcast_receiver, SOL_SOCKET, SO_REUSEADDR, &on, sizeof(on)
and I have found that this, contrary to the IP_ADD_MEMBERSHIP case,
must be called BEFORE I bind the socket!
Thanks again!
Alessandro
