+ QUdpSocket also supports UDP multicast. Use joinMulticastGroup() and
+ leaveMulticastGroup() to control group membership, and
+ QAbstractSocket::MulticastTtlOption and
+ QAbstractSocket::MulticastLoopbackOption to set the TTL and loopback socket
+ options. Use setMulticastInterface() to control the outgoing interface for
+ multicast datagrams, and multicastInterface() to query it.
+
With QUdpSocket, you can also establish a virtual connection to a
UDP server using connectToHost() and then use read() and write()
to exchange datagrams without specifying the receiver for each
datagram.
- The \l{network/broadcastsender}{Broadcast Sender} and
- \l{network/broadcastreceiver}{Broadcast Receiver} examples
