[gameprogrammer] Re: recvfrom returning 0 on UDP and blocking

["Neil Griffiths" <neil@ngriff.co.uk>]

IIRC, it's because it's possible that the previous recvfrom() didn't
flush the buffers properly and so the next time you call it to block, it
will return 0 (as in no data - not a disconnect which is impossible with
UDP as you know).

Why are you blocking anyway, is there any reason you're not using a
FD_SET ?

Why would recvfrom, on UDP and blocking, ever return 0?
