Sorry, I didn't realize your code was in C. Yes, those macros are needed, otherwise no other python threads will run while your code is being executed! In addition to wrapping functions that just take a lot of time, you should also wrap everything that could possibly block (including printf, and all blocking socket operations) -Mark C. _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
