Description

AddMulticastMembership is an abstract virtual method that specifies the interface used to allow a socket to join a multicast group address. AddMulticastMembership must be overridden and implemented in a descendant class that provides access to the protocol stack implmentation for the operating system or platform hosting the Indy library. 

Use DropMulticastMembership to remove the local IP address from the multicast group.
