## Timer 在 rtdef 中的定義

struct rt_timer
{
    struct rt_object parent;                            /**< inherit from rt_object */

    rt_list_t        row[RT_TIMER_SKIP_LIST_LEVEL];

    void (*timeout_func)(void *parameter);              /**< timeout function */
    void            *parameter;                         /**< timeout function's parameter */

    rt_tick_t        init_tick;                         /**< timer timeout tick */
    rt_tick_t        timeout_tick;                      /**< timeout tick */
};
typedef struct rt_timer *rt_timer_t;
