+/*++
+* @name IDirect3DDevice9::Present
+* @implemented
+*
+* The function IDirect3DDevice9Base_Present displays the content of the next
+* back buffer in sequence for the device.
+*
+* @param LPDIRECT3D iface
+* Pointer to the IDirect3DDevice9 object returned from IDirect3D9::CreateDevice().
+*
+* @param CONST RECT* pSourceRect
+* A pointer to a RECT structure representing an area of the back buffer to display where
+* NULL means the whole back buffer. This parameter MUST be NULL unless the back buffer
+* was created with the D3DSWAPEFFECT_COPY flag.
+*
+* @param CONST RECT* pDestRect
+* A pointer to a RECT structure representing an area of the back buffer where the
content
+* will be displayed where NULL means the whole back buffer starting at (0,0).
+* This parameter MUST be NULL unless the back buffer was created with the
D3DSWAPEFFECT_COPY flag.
+*
+* @param HWND hDestWindowOverride
+* A destination window where NULL means the window specified in the hWndDeviceWindow of
the
+* D3DPRESENT_PARAMETERS structure.
+*
+* @param CONST RGNDATA* pDirtyRegion
+* A pointer to a RGNDATA structure representing an area of the back buffer to display
where
+* NULL means the whole back buffer. This parameter MUST be NULL unless the back buffer
+* was created with the D3DSWAPEFFECT_COPY flag. This is an opimization region only.
+*
+* @return HRESULT
+* If the method successfully displays the back buffer content, the return value is
D3D_OK.
+* If no swap chains are available, the return value will be D3DERR_INVALIDCALL.
