This function waits for a message from the connected peer socket, or until time out. It returns the received message through output parameter \c OutMessage. Any error raises a Socket::Exception. For instance, it throws an exception with code Socket::eConnectionClosed if the connection is closed by the other party before message end, or with code Socket::eTimeOut if the timeout period expires before reception of any message. The timeout period can be changed using function Port::setSockOpt with parameter Socket::eRecvTimeOut.
