Description

Returns the controlling frame for frame. The controlling frame for any hierarchy of existing frames is the one that owns the thread in which the frames are running. Thus, the controlling frame for frame is not necessarily its direct owner: it may be the owner of frame's owner, and so on, depending on the depth of the hierarchy.
