Well ordinarily, a recv() on a socket is blocking to begin with, so what's the problem?
You keep calling recv() until you get your 'go to next step' message.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
