IDirectDraw (Windows Embedded CE 6.0)

1/6/2010

Applications use the methods of the IDirectDraw interface to create DirectDraw objects and work with system-level variables. For a conceptual overview, see DirectDraw in the Graphics and Multimedia guide.

The methods of the IDirectDraw interface are organized into the following groups:

Cooperative levels	IDirectDraw::SetCooperativeLevel
	IDirectDraw::TestCooperativeLevel
Creating objects	IDirectDraw::CreateClipper
	IDirectDraw::CreateSurface
Device capabilities	IDirectDraw::GetCaps
	IDirectDraw::GetDeviceIdentifier
Display modes	IDirectDraw::EnumDisplayModes
	IDirectDraw::GetDisplayMode
	IDirectDraw::GetMonitorFrequency
	IDirectDraw::RestoreDisplayMode
	IDirectDraw::SetDisplayMode
	IDirectDraw::WaitForVerticalBlank
Display status	IDirectDraw::GetScanLine
	IDirectDraw::GetVerticalBlankStatus
Miscellaneous	IDirectDraw::GetAvailableVidMem
	IDirectDraw::GetFourCCCodes
Surface management	IDirectDraw::EnumSurfaces
	IDirectDraw::FlipToGDISurface
	IDirectDraw::GetGDISurface
	IDirectDraw::GetSurfaceFromDC
	IDirectDraw::RestoreAllSurfaces

The IDirectDraw interface, like all COM interfaces, inherits the IUnknown interface methods.

The IUnknown interface supports the following three methods:

IUnknown	IUnknown::AddRef
	IUnknown::QueryInterface
	IUnknown::Release

The IDirectDraw::Initialize method is not supported in Windows Embedded CE.

You can use the LPDIRECTDRAW to declare a variable that contains a pointer to an IDirectDraw interface. The Ddraw.h header file declares this data type with the following code.

typedef struct IDirectDraw*LPDIRECTDRAW;

Requirements

Header	ddraw.h
Library	ddraw.lib
Windows Embedded CE	Windows Embedded CE 6.0 and later
