gdk-frame-clock-request-phase (frame-clock phase)

frame-clock -- a gdk-frame-clock object
phase -- the phase of type gdk-frame-clock-phase that is requested

Asks the frame clock to run a particular phase. The signal corresponding to the requested phase will be emitted the next time the frame clock processes. Multiple calls to the function gdk-frame-clock-request-phase will be combined together and only one frame processed. If you are displaying animated content and want to continually request the :update phase for a period of time, you should use the function gdk-frame-clock-begin-updating instead, since this allows GTK to adjust system parameters to get maximally smooth animations.
