    Event::set — Re-configures event

    说明

    public Event::set(
         EventBase $base ,
         mixed $fd ,
         int $what = ?,
         callable $cb = ?,
         mixed $arg = ?
    ): bool

    Re-configures event. Note, this function doesn't invoke obsolete libevent's event_set. It calls event_assign instead.

    参数

    base

    The event base to associate the event with.

    fd

    Stream resource, socket resource, or numeric file descriptor. For timer events pass -1. For signal events pass the signal number, e.g. SIGHUP.

    what

    See Event flags.

    cb

    The event callback. See Event callbacks.

    arg

    Custom data associated with the event. It will be passed to the callback when the event becomes active.

    返回值

    成功时返回 true， 或者在失败时返回 false。
