【转载】epoll_events常用事件 EPOLLIN - 当关联的文件可以执行 read ()操作时。 EPOLLOUT - 当关联的文件可以执行 write ()操作时。 EPOLLRDHUP - (从 linux 2.6.17 开始)当socket关闭的时候,或者半关闭写段的(当使用边缘触发的时候,这个标识在写一些测试代码去检测关闭的时候特别好用) EPOLLPRI - 当 read ...
3、主线程在接受到epoll反馈的事件后将事件相关数据,比如fd等加入消息队列,然后继续阻塞等待事件。 4、工作线程循环读取消息队列,以处理具体事件。当消息队列中没有可处理的事件后,挂起本线程,让出cpu资源。 5、在消息队列中有新的消息加入时需要唤醒挂起的线程,这里选用eventsfd。当没有消息后线程阻塞于eventsfd读...

event.events = EPOLLIN; event.data.ptr = (void*)fd; epoll_ctl(epfd, EPOLL_CTL_ADD, fd, event); ``` 在上面的例子中,将文件描述符 fd 设置为事件的用户数据。在事件触发时,可以通过 events.data.ptr 来获取该文件描述符。 2. 获取用户数据 当事件触发时,可以通过 events.data.ptr 来获取该事件的...
I've moved this so that it's just after the enum definition, which will hopefully make it less easy to miss if events are added/removed again in future. Fixes: 6d1077f ("vmm: Unix socket backend for serial port") vmm: update serial manager epoll events size … Verified c579890 al...
