Chapter 5 DDI Support in Display Drivers

Part 1 of this document discussed general graphics driver design and summarized DDI functions and GDI support services that are common to both printer drivers and display drivers. This chapter presents information on implementing DDI entry points that are specific to display driver design. This includes discussion in the following areas:

·Display driver initialization

·Managing desktops

·Controlling the mouse pointer

·Unloading video hardware

·Supporting coprocessor synchronization

For complete descriptions of the DDI entry points and structures, as well as GDI service functions and objects, see the Graphics Driver Reference.
