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.
