Filter to preflight or hijack clearing a scheduled hook.
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 or a WP_Error if unscheduling one or more events fails.
Parameters
$pre
null|int|false|WP_Error
Value to return instead. Default null to continue unscheduling the event.
$hook
string
Action hook, the execution of which will be unscheduled.
$args
array
Arguments to pass to the hook"s callback function.
$wp_error
bool
Whether to return a WP_Error on failure.
