What steps will reproduce the problem? 1. Try to bind UdpListeningReceiveSocket to a multicast address and send messages to the multicast group. It won't work. Suggested fix: change the Bind method in UdpSocket.cpp to: void Bind( const IpEndpointName& localEndpoint ) { struct sockaddr_in bindSockAddr; SockaddrFromIpEndpointName( bindSockAddr, localEndpoint ); if (localEndpoint.IsMulticastAddress()) { group.imr_interface.s_addr = htonl(INADDR_ANY); group.imr_multiaddr.s_addr = bindSockAddr.sin_addr.s_addr; if (setsockopt(socket_, IPPROTO_IP, IP_ADD_MEMBERSHIP, (char *)&group, sizeof(group)) < 0) { throw std::runtime_error("error adding multicast group\n"); close(socket_); exit(1); } } if (bind(socket_, (struct sockaddr *)&bindSockAddr, sizeof(bindSockAddr)) < 0) { throw std::runtime_error("unable to bind udp socket\n"); } isBound_ = true; }
