参数（Parameters）

源码（Source）

/**
 * Unschedule a previously scheduled cron job.
 *
 * The $timestamp and $hook parameters are required, so that the event can be
 * identified.
 *
 * @since 2.1.0
 *
 * @param int $timestamp Timestamp for when to run the event.
 * @param string $hook Action hook, the execution of which will be unscheduled.
 * @param array $args Arguments to pass to the hook's callback function.
 * Although not passed to a callback function, these arguments are used
 * to uniquely identify the scheduled event, so they should be the same
 * as those used when originally scheduling the event.
