NAME
exupdate - Supporting different screen update methods in a single
program. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
Example exupdate
DESCRIPTION
This program demonstrates how to support double buffering, page
flipping, and triple buffering as options within a single program, and
how to make things run at a constant rate no matter what the speed of
your computer. You have to use this example from the command line to
specify as first parameter a number which represents the type of video
update you want: 1 for double buffering with memory bitmaps, 2 for page
flipping, 3 for triple buffering and 4 for double buffering with system
bitmaps. After this, a dialog allows you to select a screen resolution
and finally you will see a kaleidoscopic animation, along with a frames
per second counter on the top left of the screen.
