/*++
* @name IDirect3DDevice9::CreateAdditionalSwapChain
* @implemented
*
* The function IDirect3DDevice9Base_CreateAdditionalSwapChain creates a swap chain object,
* useful when rendering multiple views.
*
* @param LPDIRECT3D iface
* Pointer to the IDirect3DDevice9 object returned from IDirect3D9::CreateDevice()
*
* @param D3DPRESENT_PARAMETERS* pPresentationParameters
* Pointer to a D3DPRESENT_PARAMETERS structure describing the parameters for the swap chain
* to be created.
*
* @param IDirect3DSwapChain9** ppSwapChain
* Pointer to a IDirect3DSwapChain9* to receive the swap chain object pointer.
*
* @return HRESULT
* If the method successfully fills the ppSwapChain structure, the return value is D3D_OK.
* If iSwapChain is out of range or ppSwapChain is a bad pointer, the return value
* will be D3DERR_INVALIDCALL. Also D3DERR_OUTOFVIDEOMEMORY can be returned if allocation
* of the new swap chain object failed.
*
