if root window on default screen, on default display is good enough:

Gdk::Display::get_default()->get_default_screen()->get_root_window()

here are the prototypes (Display, Screen, and Window are all in
Gdk namespace):

Glib::RefPtr<Display> Display::get_default()
Glib::RefPtr<Screen> Display::get_default_screen()
Glib::RefPtr<Window> Screen::get_root_window()

where Display::get_default() is a static, public method.
