pre_unschedule_hook
Filter HookDescription
Filter to override clearing all events attached to the hook. 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). If unscheduling one or more events fails then return either a WP_Error object or false depending on the value of the `$wp_error` parameter.Hook Information
