This function returns one of the following Direct3D 10 Return Codes. If a Direct3D 10.1 device interface can be acquired, this function succeeds and passes a pointer to the 10.1 interface using the ppDevice parameter. If a Direct3D 10.1 device interface cannot be acquired, this function returns E_FAIL, and will not return anything for the ppDevice parameter.
Remarks
For this function to succeed, you must have acquired the supplied ID3D10Device pointer using a call to the D3DX10CreateDevice function, the D3DX10CreateDeviceAndSwapChain function, the D3D10CreateDevice1 function, or the D3D10CreateDeviceAndSwapChain1 function.
You can only create a Direct3D 10.1 device on computers running Windows Vista Service Pack 1 or later, and with Direct3D 10.1-compatible hardware installed. This function will return E_FAIL on any computer not meeting these requirements. However, you can call this function on any version of Windows that has the D3DX10 DLL installed.
