NAME

       retrace_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.
