To clarify, in case I
misunderstood the various questions / replies:
Create one UDP socket
(bound to a port) for incoming datagrams. From then on, all incoming datagrams
(that are sent to that address / port) can be “replied” to with “receive_from”
and “send_to” – no additional sockets need to be created. This is a common use
case for datagrams.
