--- Comment #2 from johannes.gajdosik@gmx.at 2009-07-30 10:56:54 --- Created an attachment (id=22715) --> (http://bugs.winehq.org/attachment.cgi?id=22715) receive 2 mcast streams and distinguish the packets by mcast group
This program binds a socket to port 10000. It joins the multicast groups 239.239.239.0 and 239.239.239.2 and enters a receive-print loop. The destination address of each packet is printed. The program works well on linux (compiled with gcc) and windows (compiled with gcc, using mingw). But is does not work with wine 1.1.12 on linux.
The error message is: fixme:winsock:WS_setsockopt Unknown IPPROTO_IP optname 0x00000013
And there is also another error: when WSAIoctl would be called at the beginning, I would get:
fixme:winsock:WSAIoctl SIO_GET_EXTENSION_FUNCTION_POINTER {f689d7c8-6f1f-436b-8a53-e54fe351c322}: stub
