+/*++
+* @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.
