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.
