TIdIPMCastServer.Binding Property

Socket descriptor for multicast server transmissions.

property Binding: TIdSocketHandle;

TIdSocketHandle - Socket descriptor for the multicast server.

Binding is a read-only TIdSocketHandle property that represents the socket descriptor used by the multicast server to send datagram packets to multicast clients. 

The read access specifier for the property ensures that the Binding has been initialized, and that a datagram socket handle has been allocated and bound using the MulticastGroup address and group membership socket options. During initialization, the socket handle also received the value in the TimeToLive property. 

The value of the Loopback property is set to True during initialization of the Binding to allow diagnostics.
