Of course you do. The first argument is meant to be a GdkScreen object.
Which makes me wonder if you even read the documentation. Anyways, you
can obtain the object by invoking
gdk_screen_get_default()
and the last argument is supposed to be a priority constant like
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION
Look them up. I'd also recommend installing devhelp and gtk3-docs if
you haven't already.
