retrace_count3alleg4
Retrace count simulator. allegro game programming library.
Usage
#include <allegro.h>
extern volatile int retrace_count;
Overview
If the retrace simulator is installed, this count is incremented on each vertical retrace; otherwise, if the refresh rate is known, the count is incremented at the same rate (ignoring retraces); otherwise, it is incremented 70 times a second. This provides a way of controlling the speed of your program without installing user timer functions.
