The DrvEnableDirectDraw function enables hardware for DirectDraw use.
Handle to the PDEV returned by the driver's DrvEnablePDEV routine.
Points to the DD_CALLBACKS structure to be initialized by the driver.
Points to the DD_SURFACECALLBACKS structure to be initialized by the driver.
Points to the DD_PALETTECALLBACKS structure to be initialized by the driver.
DrvEnableDirectDraw returns TRUE if it succeeds; otherwise, it returns FALSE.
GDI calls the driver's DrvEnableDirectDraw function to obtain pointers to the DirectDraw callbacks that the driver supports. The driver should set the function pointer members of DD_CALLBACKS, DD_SURFACECALLBACKS, and DD_PALETTECALLBACKS to point to those functions that it implements. A driver should also set the corresponding bitfields in the dwFlags members of these structures for all supported callbacks.
A driver's DrvEnableDirectDraw implementation can also dedicate hardware resources such as display memory for use by DirectDraw only.
