When application uses that API, it receives one end of a datagram socket pair, which it's supposed to recv() from in order to receive mesh packets, instead of wating for *MessageReceived() calls over D-Bus. This significantly reduces system load for high traffic environment (e.g. an application that subscribes to a large number of publications in a big network). Message delivery is one way only: application is still supposed to call *Send methods via D-Bus, although the socket pair is bidirectional, so it would be possible to add sending as well.
