The IDirectDrawSurface4::GetCaps method retrieves the capabilities of the surface. These capabilities are not necessarily related to the capabilities of the display device.
HRESULT GetCaps(
LPDDSCAPS2 lpDDSCaps
);
If the method succeeds, the return value is DD_OK.
If the method fails, the return value may be one of the following error values:
DDERR_INVALIDOBJECT |
DDERR_INVALIDPARAMS |
This method differs from its counterpart in the IDirectDrawSurface3 interface in that it accepts a pointer to a DDSCAPS2 structure rather than the legacy DDSCAPS structure.
