Update of patch #9169 (project lwip): Status: None => Invalid Open/Closed: Open => Closed _______________________________________________________ Follow-up Comment #2: Simply don't call udp_connect() and you will receive all multicast traffic on that PCB automatically. udp_connect() means: 1) If I call udp_send() somewhere, it should go to the specified remote address/port. 2) I _only_ want to receive from the specified remote IP address/port. Note: I'm currently thinking about reverting your last patch, because you can get your desired behavior in this case by also not calling udp_connect() and comparing the source IP as the first thing to do in your udp_recv() function. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?9169> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
