Remarks

You can query this structure from the driver using GetDriverInfo with GUID_VideoPortCallbacks.

This structure contains the entry points in the display driver that DirectDraw calls. Entries that the display driver does not use should be set to NULL.

Requirements

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
Header: Ddrawi.h.
