CFRunLoopSourceSignal(_:)
Signals a CFRunLoopSource object, marking it as ready to fire.
Declaration
func CFRunLoopSourceSignal(_ source: CFRunLoopSource!)Parameters
- source:
The run loop source to signal.
Discussion
This function has no effect on version 1 sources, which are automatically handled when Mach messages arrive for them. After signaling a version 0 source, you need to call CFRunLoopWakeUp(_:) on one of the run loops in which the source is registered to get the source handled immediately.
