Description Description
Returning a non-null value will short-circuit the normal unscheduling process, causing the function to return the filtered value instead.
For plugins replacing wp-cron, return the number of events successfully unscheduled (zero if no events were registered with the hook) or false if unscheduling one or more events fails.
Parameters Parameters
- $pre
-
Value to return instead. Default null to continue unscheduling the hook.
- $hook
-
Action hook, the execution of which will be unscheduled.
