Defined at:

Filter to override unscheduling of events.

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 true if the event was successfully unscheduled, false or a WP_Error if not.


$pre = apply_filters( 'pre_unschedule_event', null, $timestamp, $hook, $args, $wp_error );
