man中给出了epoll的用法，example如下：       for(;;) {           nfds = epoll_wait(kdpfd, events, maxevents, -1);           for(n = 0; n                if(events[n].data.fd == listener) {                   client

Here are the different values that the s, stat and state output specifiers(header "STAT" or "S") will display to describe the state of a process.D    Uninterruptible sleep (usually IO)R    Running or

一旦我们建立了连接,我们的下一步就是进行通信了.在Linux下面把我们前面建立的通道 看成是文件描述符,这样服务器端和客户端进行通信时候,只要往文件描述符里面读写东西了. 就象我们往文件读写一样.  1 写函数write   ssize_t write(int fd,const void *buf,size_t nbytes) write函数将buf中的nbytes字节内容写入文件描述符fd.成功
