How check if multicast socket is occupied?

Question

I need to send some stream on multicast.
Is there some way to check ( from the code ) is some multicast socket is occupied by someone else on the network that i connected to ?

Answer 1

There is no such thing. Multicast can be one to many or many to one. Depends on your application/problem. Usually a sender just sends to a group:port and receivers join to listen.
