   Allegro interrupt handlers
  I know that I sound like a n00b, but how can I use these to slow down my game?  So far, I understand that I need to put one before my rendering code to stop the program at that point, and calculate the framerate, but what I should actually put there is beyond me...I have a good game already, all I really need is to make it run the same speed on all computers.  I understand the rest(); function, but I need my game to run smoother, and at a constant rate. What should I do?BTW, the allegro function I am trying to use is install_int_ex(void(*proc)(), int speed);It basically adds a user created timed function to allegro's list, and is standard in the allegro library. The speed is in milliseconds.
