Chapter 1 Graphics Driver Functions

This chapter provides information on the following function groups:

• DrvXxx functions. These functions are implemented by graphics drivers, and are called by GDI.

• EngXxx functions. These functions are system-supplied GDI services that can be called by graphics drivers.

• XXXOBJ_Xxx functions. These specialized service routines are implemented within GDI. They are available to be called by graphics drivers.

The Graphics Driver Design Guide describes which DrvXxx functions are required, conditionally required, or optional in a graphics driver’s implementation.
