Hi,
Sorry, if this thread doesnt fit here. I will still ask.
I want to wait for a certain timeout value (60 secs) after sending a request packet over a TCP socket, before deciding if the peer is dead or alive. If the reply packet comes within 60 secs from starting timer, I need to stop the timer and proceed further.
How can I implement this functionality with TCP recv() function? Any pointers ?
Thanks,
Consider looking at select. Make a time stamp for each connection. Call select in a loop every so often. If that function isn't ready for reading or writing (depending on what you're doing) by the time your time runs out, close the connection. There's probably a better way to do it, but that should work.
Also consider searching for Beej's guide to sockets.

Hope is the first step on the road to disappointment.
Hi quzah,
I wanted to check the timeout during connect() as well as send()/recv() state. I googled for it and found a way to do it using setsockopt(). Following was my solution.
It worked just fine.Code:struct timeval tv; tv.tv_sec = 30; /* Timeout in seconds */ setsockopt(sockid, SOL_SOCKET, SO_SNDTIMEO,(struct timeval *)&tv,sizeof(struct timeval)); setsockopt(sockid, SOL_SOCKET, SO_RCVTIMEO,(struct timeval *)&tv,sizeof(struct timeval));
Thanks
