- [DLL]h - handle to UDPTransport object that was returned by Create method
- GroupAddress - Multicast address of the group
- BindAddress - Interface to bind the address to
- TTL - The number of "hops" to pass for multicast message
- Loop - Defines if the message is sent to the socket which sent the original message
Use this method to add a multicast socket to the group. Adding to the group is necessary to send or receive messages using multicast address.
GroupAddress specifies the multicast address (in range 224.0.0.1-239.255.255.255) to which the messages are sent or from which the messages are received.
BindAddress defines the interface to bind to. This one can be empty, in which case the socket is bound to default interface. Note that binding to default interface doesn't mean "any" interface (as it is with binding regular sockets).
TTL defines the number of gateawys to send the message to. This value is platform-specific, please consult the manual for more details.
Loop defines if the message sent to the multicast address is received by the sender socket.
Note, that if the transport is active, this method restarts the transport so that sockets are initialized with participation in multicast group.
