    ZMQDevice::setTimerCallback — Set the timer callback function

    说明

    public function ZMQDevice::setTimerCallback(callable $cb_func, int $timeout, mixed $user_data = ?): ZMQDevice

    Sets the timer callback function. The timer callback will be invoked after timeout has passed. The difference between idle and timer callbacks are that idle callback is invoked only when the device is idle. The callback function signature is callback (mixed $user_data). Added in ZMQ extension version 1.1.0.

    参数

    cb_func
    Callback function to invoke when the timer fires. Returning false or a value that evaluates to false from this function will cause the device to stop.
    timeout
    How often to invoke the timer callback in milliseconds. The timer callback is invoked periodically. The timeout value guarantees that there is at least this amount of milliseconds between invocations of the callback function.
    user_data

    Additional data to pass to the callback function.

    返回值

    On success this method returns the current object.
