总结: man中给出了epoll的用法,example程序如下: for(;;) { nfds = epoll_wait(kdpfd, events, maxevents, -1); for(n = 0; n < nfds; ++n) { if(events[n].data.fd == listener) { client = accept(listener, (struct sockaddr *) &local, &addrlen); if(client < 0){ perror("accept...

The following code creates anepoll_waitinstance. For the callable service, useepoll_wait (BPX1EPW, BPX4EPW) — Wait for an I/O event on an epoll file descriptor. AMODE 64 callers use theBPX4EPW (epoll_wait) example. For the data structure, seeBPXYEPOL— Map epoll syscall parameters....

在linux新的内核中,有了一种替换它的机制,就是epoll。相比于select,epoll最大的好处在于它不会随着监听fd数目的增长而降低效率。因为在内核中的select实现中,它是采用轮询来处理的,轮询的fd数目越多,自然耗时越多。并且,linux/posix_types.h头文件有这样的声明:...
以example/echo_c++/server.cpp为例测试:在Echo函数中添加如下代码,再分别启动echo_server echo_client即可复现。 注:可以在event_dispatcher.cpp中打印epoll_wait的协程id,再通过内置服务接口验证about_to_quit是否置1 `brpc::Channel ch; brpc::ChannelOptions options; options.protocol = "http"; //8888 not ...
