best way to init in c++?(DX9)

Hello, i'm trying to find the best way to init in c++, i'v tryed
pointing _HAL -> _REF&32...

what is better? (i'm using the most simple init possible)

void initD3D(HWND hWnd)
{
    d3d = Direct3DCreate9(D3D_SDK_VERSION); // create the Direct3D
interface

    D3DPRESENT_PARAMETERS d3dpp; // create a struct to hold various
device information

    ZeroMemory(&d3dpp, sizeof(d3dpp)); // clear out the struct for
use
    d3dpp.Windowed = TRUE; // program windowed, not fullscreen
    d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; // discard old frames
    d3dpp.hDeviceWindow = hWnd; // set the window to be used by
Direct3D

    // create a device class using this information and the info from
the d3dpp stuct
    d3d->CreateDevice(D3DADAPTER_DEFAULT,
                      D3DDEVTYPE_HAL,
                      hWnd,
                      D3DCREATE_SOFTWARE_VERTEXPROCESSING,
                      &d3dpp,
                      &d3ddev);

    return;
}

thanks for the help :)
