b) here is most important problem: that is that the i/o thread you don't want it to eat a full core. So basically you need to call Sleep there.

I have it sleep 10 milliseconds for example each time. Now that seems fine, except when you want to play super superbullet type games with your engine.

Hi Vincent,

I wonder why you sleep in the I/O thread? I have a plain while ( fgets() ) loop and haven't noticed the I/O thread eat any CPU time. Perhaps you read the input in a different way?
I thought that fgets on stdin should always be blocking...

Martin

Actually I wondered about exactly the same thing. A blocking read does not eat CPU time. Sleep() is not appropriate here IMO.

Sven


You cannot do blocking read of course in the thread that commands the search. A 3d thread is used for that in Diep in its own DEP protocol.
