[Flightgear-devel] Sockets

[John Wojnaroski]

Hi,   Running FG under cygwin allows the socket output to be set to the broadcast address, 192.xxx.xxx.255. But under linux Fg returns an error that make_client_socket failed for the broadcast address. Looks like cygwin is faking it.   there are socket options with the system call of  'int setsockopt(int sockfd, int level, int optname, char *val, int len) to permit the sending of broadcast msgs. Broadcasting is only allowed for datagram sockets and only on networks that support broadcst msgs. Since the linux kernel does not provide a capability to simulate braodcast, the cygwin system must be doing something to mimic the broadcast.   From the source in sg_socket, it looks like the plib netSocket::connect is making the system call to connect.   IMHO a broadcast capability for a flight sim is a gotta-have. Has anyone approached then plib folks (Steve Baker et al) on this subject?   Regards John W.
