Can a socket join more than one multicast group?

Question

I am implementing an application intends a socket to join more than multicast group? So, Can a socket join more than one multicast group?

Could you elaborate why you don't want to just create more sockets? — billyswong, Dec 13 '12 at 08:33

The longer answer is: yes, you can, using the appropriate setsockopt() call with the IP_ADD_MEMBERSHIP option (quote: https://stackoverflow.com/a/9258030/1284631)

@user1680544 It doesn't make any difference whether you bind on `INADDR_ANY`, unless some of the multicast groups require non-standard routine. – user207421 Dec 13 '12 at 09:49
Err, sorry, routine => routing. – user207421 Dec 14 '12 at 21:27
