Arguments

:: Binary a

=> HostName

Multicast IP

-> PortNumber

Port number

-> Int

Maximum message size

-> IO (IO (a, SockAddr), a -> IO ())

Given a hostname and a port number, initialize the multicast system.

Note: it is important that you never send messages larger than the maximum message size; if you do, all subsequent communication will probably fail.

Returns a reader and a writer.

NOTE: By rights the two functions should be "locally" polymorphic in a, but this requires impredicative types.
