While every attempt has been made to avoid significant deviation in DDGPEfrom the Desktop DDHAL specification, there are still several steps that must be taken to convert from one model to the other.
This chapter discusses what is necessary to convert a DDHAL Desktop implementation into a DDGPE-compatible Windows CE DDHAL implementation. While the conversion to a device driver that is not derived from DDGPEis not specifically discussed, this chapter will still be of use to developers who have decided to ignore DDGPE.
Before you start porting any DDHAL display driver from a Desktop implementation, you should already have a working DDGPE-based driver. Make sure you have followed the steps outlined in Creating a DirectDraw Display Driverto create a driver that you can modify with the code in your Desktop DDHAL.
