IDirect3D2::CreateViewport

The IDirect3D2::CreateViewport method creates a Direct3DViewport object. The viewport is associated with a Direct3DDevice object by using the IDirect3DDevice2::AddViewport method.

HRESULT CreateViewport(
  LPDIRECT3DVIEWPORT2* lplpD3DViewport2,  
  IUnknown* pUnkOuter                     
);
 

Parameters

lplpD3DViewport2

Address that will be filled with a pointer to an IDirect3DViewport2 interface if the call succeeds.

pUnkOuter

This parameter is provided for future compatibility with COM aggregation features. Currently, however, the IDirect3D2::CreateViewport method returns an error if this parameter is anything but NULL.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value may be one of the following values:

DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS

Remarks

In the IDirect3D interface, this method retrieves a pointer to an IDirect3DViewport interface, not an IDirect3DViewport2 interface.
