[En-Nut-Discussion] UdpReceiveFrom() blocking?

Hello,

my previous problem seems to be resolved so in order to keep you busy,
here's another one... :-)

It looks like the UdpReceiveFrom() function blocks even when I use it with
timeout = 0. A fast look over the source revealed there's a call to
NutEventWait() which switches threads regardless of the timeout value.
Maybe I just got it all wrong... I know the timeout value is limited by
the system timer granularity but 0 should be a special case. Just look if
there's data available, and if not, just return immediately (no events and
thread switches)...

Radek
