pre_clear_scheduled_hook │ хук-фильтр │ WP 5.1.0

Filter to preflight or hijack clearing a scheduled 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) or false if unscheduling one or more events fails.
