retrace_count(3) Allegro manual retrace_count(3)NAMEretrace_count - Retrace count simulator. Allegro game programming
library.
SYNOPSIS
#include <allegro.h>
extern volatile int retrace_count;
DESCRIPTION
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.
