IDirect3DDevice9::GetViewport Method

Retrieves the viewport parameters currently set for the device.

Syntax

HRESULT GetViewport(      

    D3DVIEWPORT9 *pViewport
);

Parameters

pViewport
[out] Pointer to a D3DVIEWPORT9 structure, representing the returned viewport parameters.

Return Value

If the method succeeds, the return value is D3D_OK.
D3DERR_INVALIDCALL is returned if the pViewport parameter is invalid.

Remarks

Typically, methods that return state will not work on a device that is created using D3DCREATE_PUREDEVICE. This method is an exception, because Microsoft?Direct3D?needs to track viewport data, even on a pure device.
