Calling multicastSender creates a client side UDP socket for sending multicast datagrams to the specified host and port.

Minimal example:

 import Network.Socket
 import Network.Multicast
 main = withSocketsDo $ do
     (sock, addr) <- multicastSender "224.0.0.99" 9999
     let loop = do
         sendTo sock "Hello, world" addr
         loop in loop

Calling multicastReceiver creates and binds a UDP socket for listening multicast datagrams on the specified host and port.

Minimal example:

 import Network.Socket
 import Network.Multicast
 main = withSocketsDo $ do
     sock <- multicastReceiver "224.0.0.99" 9999
     let loop = do
         (msg, _, addr) <- recvFrom sock 1024
         print (msg, addr) in loop

Make the socket listen on multicast datagrams sent by the specified HostName.

Stop the socket from listening on multicast datagrams sent by the specified HostName.

Enable or disable the loopback mode on a socket created by multicastSender. Loopback is enabled by default; disabling it may improve performance a little bit.

Set the Time-to-Live of the multicast.

Set the outgoing interface address of the multicast.
