join_multicast_group

Registers this to receive multicast messages sent to group.

this must be a g_socket_type_datagram socket, and must have been bound to an appropriate interface and port with bind.

If iface is null, the system will automatically pick an interface to bind to based on group.

If source_specific is true, source-specific multicast as defined in RFC 4604 is used. Note that on older platforms this may fail with a g_io_error_not_supported error.

Parameters:

this	a Socket.
group	a InetAddress specifying the group address to join.
source_specific	true if source-specific multicast should be used
iface	Name of the interface to use, or null

Returns:

true on success, false on error.
