    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.
    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.

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

    The crows maintain that a single crow could destroy the heavens. Doubtless this is so. But it proves nothing against the heavens, for the heavens signify simply: the impossibility of crows.
