python实现Linux异步epoll代码

复制代码

代码如下:

import socket

import select

if __name__==”__main__”:

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

    s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)

s.bind((“”,20123))

    s.listen(10)

    epoll=select.epoll()

    print s.fileno()

    print select.EPOLLIN|select.EPOLLET

epoll.register(s.fileno(),select.EPOLLIN|select.EPOLLET)

    while 1:

        epoll_list=epoll.poll()

for fd,events in epoll_list:

            print fd

            print events

            if fd==s.fileno():

                conn,addr=s.accept()

                print 123
