Function

CFRunLoopTimerGetContext(_:_:)

Returns the context information for a CFRunLoopTimer object.

Declaration

func CFRunLoopTimerGetContext(_ timer: CFRunLoopTimer!, _ context: UnsafeMutablePointer<CFRunLoopTimerContext>!)

Parameters

timer

The run loop timer to examine.

context

A pointer to the structure into which the context information for timer is to be copied. The information being returned is the same information passed to CFRunLoopTimerCreate(_:_:_:_:_:_:_:) when creating timer.

Discussion

The context version number for run loop timers is currently 0. Before calling this function, you need to initialize the version member of context to 0.
