libgesturesDescription:
This callback function is invoked when the gesture set fails. The gesture set fails when all gestures in the set transition to the FAILED state. The callback is passed the list of events leading up to the failure, so that those events can be passed to another gesture set, if necessary.
The
async
parameter indicates which thread invoked the callback:- the thread that called
gestures_set_process_event()
(async
== 0) - the timer thread (
async
== 1)
Returns:
Nothing.
