No - that's precisely the wrong thing to do.
If you set "block = 1", then the agent *will* block in the select call,
and will do so indefinitely.
What you probably need to do is to set the contents of the timeout structure
to be 0. Not NULL (which means block), but 0.
Look a little bit earlier where it says
tvp->tv_sec = SOMETHING;
tvp->tv_usec = SOMETHING;
and set both of those to be 0.
That should do the trick...
