The following functions are exported by DDGPE.LIB. They are completely functional and suitable for a real world DirectDraw HAL implementation. However, you will likely need to augment or completely replace many of them with your own implementations in order to extend and optimize your driver.
Each of these functions has a corresponding element in a DirectDraw HAL callback structure. You should consult the DirectDraw HAL documentation in the DirectDraw DDK for more information on these DDHAL functions.
