This method duplicates a DirectDrawSurface object.

HRESULT DuplicateSurface( 
  LPDIRECTDRAWSURFACE4 lpDDSurface, 
  LPLPDIRECTDRAWSURFACE4 FAR* lplpDupDDSurface
);

Parameters

• lpDDSurface
  Address of the IDirectDrawSurface4 interface for the surface to be duplicated.
• lplpDupDDSurface
  Address of a variable that will be filled with an IDirectDrawSurface5 interface pointer for the newly duplicated DirectDrawSurface object.

Remarks

This method creates a new DirectDrawSurface object that points to the same surface memory as an existing DirectDrawSurface object. This duplicate can be used just like the original object. The surface memory is released after the last object referencing it is released. A primary surface, 3-D surface, or implicitly created surface cannot be duplicated.
