I'm struggling with that for quite some time already.  wmctrl uses it
but I never got anything from a call like

  rc = XGetWindowProperty (dpy, dpyinfo->root_window,
                           XInternAtom (dpy, "_NET_WM_NAME", False),
                           0, max_len, False, XA_STRING,
/**                        XInternAtom (dpy, "UTF8_STRING", False), **/
                           &actual_type, &actual_format, &actual_size,
                           &bytes_remaining, &name);

It reports success but name remains NULL.  If you have any clues about
what I'm doing wrong I'd be all ears.
