This chapter provides reference pages for the DirectDraw hardware interface and DirectDraw-specific DDI functions currently supported in Windows NT. Except for the DrvXxx functions, all other function names are pseudonames to be decided upon by the display driver writer.
Driver writers must include both ddrawint.h and ddraw.h in their driver. The former include file is provided with the Windows NT DDK; the latter is shipped with the Win32 SDK.
For DirectDraw hardware interface data structure definitions, see DirectDraw Hardware Interface Structures.
