struct rt_object_information { enum rt_object_class_type type; /**< object class type */ rt_list_t object_list; /**< object list */ rt_size_t object_size; /**< object size */ }; 其中,type 是用一个枚举类型实现的,具体实现如下: 代码语言:txt AI代码解释 enum rt_object_info_type...

在 rt_thread 中,是通过一个全局数组的形式实现的,数组的类型是 rt_object_information ,rt_object_information 的实现代码如下: struct rt_object_information { enum rt_object_class_type type; /**< object class type */ rt_list_t object_list; /**< object list */ rt_size_t object_size; /**...

Python底层通过调用函数PyType_Ready对内建对象进行初始化,实际上,PyType_Ready不仅仅是处理内建对象,还会处理class对象,并且PyType_Ready对于内建对象和class对象的作用还不同。比如PyList_Type,它在底层是已经被定义好了的,所以在解释器启动的时候就直接创建,并且是全局对象。只不过我们说它还是不够完善,还需要再打...
