对于Edge Triggered (ET) 边沿触发: [5]遍历epoll的ready_list,将sk从ready_list中移除,然后调用该sk的poll逻辑收集发生的事件 对于Level Triggered (LT) 水平触发: [5.1]遍历epoll的ready_list,将sk从ready_list中移除,然后调用该sk的poll逻辑收集发生的事件[5.2]如果该sk的poll函数返回了关心的事件(对于可读事...
LT模式即Level Triggered工作模式。 与ET模式不同的是,以LT方式调用epoll接口的时候,它就相当于一个速度比较快的poll,无论后面的数据是否被使用。 LT(level triggered):LT是缺省的工作方式,并且同时支持block和no-block socket。在这种做法中,内核告诉你一个文件描述符是否就绪了,然后你可以对这个就绪的fd进行IO操作。
Edge和Level触发的中断 异步I/O中的Edge-Triggered和Level-Triggered是非常重要的概念;Edge-Triggered字面上理解就是指“边界触发”,说的是当状态变化的时候触发,以后如果状态一直没有变化或没有重新要求系统给出通知,将不再通知应用程序;Level-Triggered是指“状态触发”,说的是在某种状态下触发,如果一直在这种状态下...
The epoll event distribution interface is able to behave both as edge-triggered (ET) and as level-triggered (LT). The difference between the two mechanisms can be described as follows. Suppose that this scenario happens: The file descriptor that represents the read side of a pipe (rfd) is ...
基于控制循环的"level-triggered"实现比事件驱动的"edge-triggered"方式可以提供更加健壮的分布式系统实现，...
epoll 最开始只有 Edge Triggered API (ET API),因为实在不好懂容易出错,所以 epoll 作者 Davide Libenzi 再加入了 Level Triggered API:lt-epoll ( lev...
