timeout problem

ALLERSLIT

Hey, this is my code:

connect(s, (SOCKADDR\*) &addrin, sizeof(addrin));

send(s, stRequest.c\_str(), stRequest.length(), 0);
cout << "stRequest sent." << endl;
recv(s, buffer, sizeof(buffer), 0);
cout << "buffer received." << endl;

Now this works perfectly fine if the webserver is working well, but sometimes it just sits there trying to recv() forever.. Iam not exactly sure what causes it but either way, I need a way to set a timeout or something similiar.. I couldn't really find something helpfull on google, so yea I thought maybe you guys could help me out.

You can use WSARecv or an overlapped socket. http://support.microsoft.com/kb/181611[^]

There are multiple choices: - adjust the send/receive timeouts with setsockopt(), see SO_SNDTIMEO and SO_RCVTIMEO
- use non-blocking/asynchronous sockets, makes event based applications so much easier - use a C++ networking library/API offering timeouts or search for a HTTP client class, would be my recommendation
Happy coding! :)
