28This class implements a trivial multi target socket.
29The triviality refers to the fact that the socket does not
30do blocking to non-blocking or non-blocking to blocking conversions.
31
32It allows to connect multiple initiators to this socket.
33The user has to register callbacks for the fw interface methods
34he likes to use. The callbacks are basically equal to the fw interface
35methods but carry an additional integer that indicates to which
36index of this socket the calling initiator is connected.
