IDirectDrawSurface7::EnumAttachedSurfaces method (ddraw.h)

  • Article

Enumerates all the surfaces that are attached to this surface.

Syntax

HRESULT EnumAttachedSurfaces(
  [in] LPVOID                    unnamedParam1,
  [in] LPDDENUMSURFACESCALLBACK7 unnamedParam2
);

Parameters

[in] unnamedParam1

Address of the application-defined structure that is passed to the enumeration member every time that it is called.

[in] unnamedParam2

Address of the EnumSurfacesCallback7 function to be called for each surface that is attached to this surface.

Return value

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

EnumAttachedSurfaces 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.

EnumAttachedSurfaces differs from its counterparts in previous interface versions in that it accepts a pointer to an EnumSurfacesCallback7 function, rather than an EnumSurfacesCallback or EnumSurfacesCallback2 function.
