Return Values
Errors are represented by negative values and cannot be combined. This table lists the values that can be returned by all methods of the IDirectDraw7, IDirectDrawSurface7, IDirectDrawPalette, IDirectDrawClipper, IDDVideoPortContainer, and IDirectDrawVideoPort interfaces. For a list of the error codes that each method can return, see the method description.
