Hello..

Im working on udp non-blocking socket. I looked around but I couldnt find any good article or example on it.. How do I have to set udp socket to non-blocking?

Thanks

Code:

       It is possible to do non-blocking IO on sockets by setting the O_NONBLOCK flag on a
       socket file descriptor using fcntl(2).  Then all operations that would  block  will
       (usually)  return  with EAGAIN (operation should be retried later); connect(2) will
       return EINPROGRESS error.  The user can then wait for various events via poll(2) or
       select(2).

Well if you're using Linux anyway.

If you're on fairly broken windows, you'd better say so.

You could try ACE library, which is a portable network library:
