getComplete

Returns whether @timings are complete.

The timing information in a GdkFrameTimings is filled in incrementally as the frame as drawn and passed off to the window system for processing and display to the user. The accessor functions for GdkFrameTimings can return 0 to indicate an unavailable value for two reasons: either because the information is not yet available, or because it isn't available at all.

Once this function returns true for a frame, you can be certain that no further values will become available and be stored in the GdkFrameTimings.
