凡是可作用于next()函数的对象都是Iterator类型;它们表示一个惰性计算的序列; 集合数据类型如list、dict、str等是Iterable但不是Iterator, 不过可以通过iter()函数获得一个Iterator对象; Python的for循环本质上就是通过不断调用next()函数实现的. 3.在页脚html代码添加如下内容,会增加打赏功能: 1 2 3 4 5 6 7 ...
build时就会报错了,更别提执行了 怎么做呢?需要把Kernel的函数封装到一个Handler里,然后把这个Handler注册到系统的System Call Group里。然后,RTP里通过操作系统提供的Trap来访问这个Handler。 第一步:在Kernel里创建struct数据类型,用来表示Kernel函数的入参
