IDirect3DDevice3::AddViewport

The IDirect3DDevice3::AddViewport method adds the specified viewport to the list of viewport objects associated with the device and increments the reference count of the viewport.

HRESULT AddViewport(
  LPDIRECT3DVIEWPORT3 lpDirect3DViewport  
);

Parameters

lpDirect3DViewport: Address of the IDirect3DViewport3 interface that should be associated with this Direct3DDevice object.

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

This method will fail, returning DDERR_INVALIDPARAMS, if you attempt to add a viewport that has already been assigned to the device.

In the IDirect3DDevice2 interface, this method accepts a pointer to an IDirect3DViewport interface, not an IDirect3DViewport3 interface.
