+/*++
+* @name IDirect3DDevice9::GetFrontBufferData
+* @implemented
+*
+* The function IDirect3DDevice9Base_GetFrontBufferData copies the content of
+* the display device's front buffer in a system memory surface buffer.
+*
+* @param LPDIRECT3D iface
+* Pointer to the IDirect3DDevice9 object returned from IDirect3D9::CreateDevice().
+*
+* @param UINT iSwapChain
+* Swap chain index to get object for.
+* The maximum value for this is the value returned by IDirect3DDevice9::GetNumberOfSwapChains() - 1.
+*
+* @param IDirect3DSurface9* pDestSurface
+* Pointer to a IDirect3DSurface9 to receive front buffer content
+*
+* @return HRESULT
+* If the method successfully fills the pDestSurface buffer, the return value is D3D_OK.
+* If iSwapChain is out of range or pDestSurface is a bad pointer, the return value
+* will be D3DERR_INVALIDCALL.
