Hello, in "UNP, Vol.1" from R.W.Stevens I've read on page 505 to call bind() for a reciving multicast socket (in order to recive only multicast package instead of additional udp packages). Is it euqivalent to call connect() (UNP, Vol.1, p. 224) for that udp socket (because to get it 'connected')? A connected udp socket should only recive packages from the address specified in the connect(). with best regards, Oliver - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
