Function

CFRunLoopSourceSignal

Signals a CFRunLoopSource object, marking it as ready to fire.

Declaration

void CFRunLoopSourceSignal(CFRunLoopSourceRef source);

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.
