IDirectDrawClipper::Initialize

The IDirectDrawClipper::Initialize method initializes a DirectDrawClipper object that was created by using the CoCreateInstance COM function.

HRESULT Initialize(
  LPDIRECTDRAW lpDD,  
  DWORD dwFlags       
);
 

Parameters

lpDD

Address of the DirectDraw structure that represents the DirectDraw object. If this parameter is set to NULL, an independent DirectDrawClipper object is created (the equivalent of using the DirectDrawCreateClipper function).

dwFlags

This parameter is currently not used and must be set to 0.

Return Values

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:

This method is provided for compliance with the Component Object Model (COM) protocol. If DirectDrawCreateClipper or the IDirectDraw2::CreateClipper method was used to create the DirectDrawClipper object, this method returns DDERR_ALREADYINITIALIZED.
