Hi all, I am struggling with streamutil.c to implement multicast sender and receiver. On pure socket level, it is for me quite clear what to do, but I didn't find the pj level of abstraction to get it running with streamutil. In the Socket Abstraction, there's a pj_sock_setsockopt(..) but in streamutil, there's no sockfd and I see no way to get it. Do I have to use pj_ip_mreq instead and if so, how ? pj_IP_MULTICAST_IF and pj_IP_ADD_MEMBERSHIP should also be used somehow I guess ? Cheers, Frederic
