CFRunstructure that was used when creating the run loop source.
Loop Source Context
You only need to provide this callback if you create your own version 0 run loop source. CFSocket run loop sources already implement this callback to forward the received message to the CFSocket’s own callback function, which you do need to implement.
You specify this callback in the
