retrace_count(3)		Allegro	manual		      retrace_count(3)

NAME
       retrace_count  -	 Retrace count simulator. Allegro game programming li-
       brary.

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.
