Hi Jan
I am currently trying to just write a client/server for a robot device and would has to initially send something from client to the server and guarantee its arrival ( handshake for crucial data). Has RTnet got any function that allows user to do timeouts for recvfrom or anything for basic checks.
Default behaviour of all receive functions is to block until message arrives. You can set a timeout with
ioctl_rt(sock, RTNET_RTIOC_TIMEOUT, &nanoseconds)
since version 0.7.0 or
rt_socket_setsockopt(sock, SOL_SOCKET, RT_SO_TIMEOUT, &timeout,
sizeof(timeout))in earlier versions.
