title: Can a socket be made non-blocking only for the recv() function?
body: <p>I want to be able to call <code>recv()</code> without having to block, so I want to make it non-blocking, but I do not want it to be non blocking when sending data. So can a socket be made non-blocking only for the <code>recv()</code> function, or does the blocking/non-blocking mode affects all of the socket functions?</p>
