### IDirectDraw2::CreateSurface

The IDirectDraw2::CreateSurface method creates a DirectDrawSurface object for this DirectDraw object.

HRESULT CreateSurface(

LPDDSURFACEDESC lpDDSurfaceDesc,

LPDIRECTDRAWSURFACE FAR *lplpDDSurface,

IUnknown FAR *pUnkOuter

);

##### Parameters

lpDDSurfaceDesc
  Address of the DDSURFACEDESC structure that describes the requested surface. You should set any unused members of DDSURFACEDESC to zero before calling this method. A DDSCAPS structure is a member of DDSURFACEDESC.
lplpDDSurface
  Address of a pointer to be initialized with a valid DirectDrawSurface pointer if the call succeeds.
pUnkOuter
  Allows for future compatibility with COM aggregation features. Presently, however, IDirectDraw2::CreateSurface returns an error if this parameter is anything but NULL.

##### Return Values
