exaccel(3)                      Allegro manual                      exaccel(3)



NAME
       exaccel - Using offscreen video memory to store source graphics for
       VBE/AF. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       Example exaccel

DESCRIPTION
       This program demonstrates how to use an offscreen part of the video
       memory to store source graphics for a hardware accelerated graphics
       driver. The example loads the `mysha.pcx' file and then blits it
       several times on the screen. Depending on whether you have enough video
       memory and Allegro supports the hardware acceleration features of your
       card, your success running this example may be none at all, sluggish
       performance due to software emulation, or flicker free smooth hardware
       accelerated animation.
