IDirectDrawSurface7::EnumAttachedSurfaces

The IDirectDrawSurface7::EnumAttachedSurfaces method enumerates all the surfaces attached to a given surface.

HRESULT EnumAttachedSurfaces(
  LPVOID lpContext,                                
  LPDDENUMSURFACESCALLBACK2 lpEnumSurfacesCallback  
);

Parameters

lpContext
Address of the application-defined structure that is passed to the enumeration member every time that it is called.
lpEnumSurfacesCallback
Address of the EnumSurfacesCallback2 function to be called for each surface that is attached to this surface.

Return Values

If the method succeeds, the return value is DD_OK.

If it fails, the method can return one of the following error values:

DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_SURFACELOST

Remarks

This method enumerates only those surfaces that are directly attached to this surface. For example, in a flipping chain of three or more surfaces, only one surface is enumerated because each surface is attached only to the next surface in the flipping chain. In such a configuration, you can call EnumAttachedSurfaces on each successive surface to walk the entire flipping chain.

This method differs from its counterparts in previous interface versions in that it accepts a pointer to an EnumSurfacesCallback2 function, rather than an EnumSurfacesCallback function.
