这家伙很懒，什么也没写！

找到程序卡的地方了卡在了 node = node->next;![de91377962be85586acb461128865ced.png](https://oss-club.rt-thread.org/uploads/20210313/de91377962be85586acb461128865ced.png)
```c
static rt_list_t *list_get_next(rt_list_t *current, list_get_next_t *arg)
{
    int first_flag = 0;
    rt_ubase_t level;
    rt_list_t *node, *list;
    rt_list_t **array;
    int nr;

arg->nr_out = 0;

if (!arg->nr || !arg->type)
    {
        return (rt_list_t *)RT_NULL;
    }

list = arg->list;

if (!current) /* find first */
    {
        node = list;
        first_flag = 1;
    }
    else
    {
        node = current;
    }

level = rt_hw_interrupt_disable();

if (!first_flag)
    {
        struct rt_object *obj;
        /* The node in the list? */
        obj = rt_list_entry(node, struct rt_object, list);
        if ((obj->type & ~RT_Object_Class_Static) != arg->type)
        {
            rt_hw_interrupt_enable(level);
            return (rt_list_t *)RT_NULL;
        }
    }

nr = 0;
    array = arg->array;
    while (1)
    {
        node = node->next;
        if (node == list)
        {
            node = (rt_list_t *)RT_NULL;
            break;
        }
        nr++;
        *array++ = node;
        if (nr == arg->nr)
        {
            break;
        }
    }
    
    rt_hw_interrupt_enable(level);
    arg->nr_out = nr;
    return node;
}
