一、使用alarm 函数设置超时 代码语言:cpp 复制 voidhandler(intsig){}signal(SIGALRM,handler);alarm(5);intret=read(fd,buf,sizeof(buf));if(ret==-1&&errno==EINTR)errno=ETIMEOUT;elseif(ret>=0)alarm(0);... 程序大概框架如上所示,如果read在5s内被SIGALRM信号中断而返回,则表示超时,否则未超时已...
Sockets are a mechanism for exchanging data between processes. These processes can either be on the same machine, or on different machines connected via a network. Once a socket connection is established, data can be sent in both directions until one of the endpoints closes the connection The g...

参考资料:http://c.biancheng.net/cpp/socket/ http://www.winsocketdotnetworkprogramming.com/ socket 是“套接字”意思,是计算机之间进行通信的一种约定。 通过 socket 这种约定,一台计算机可以接收其他计算机的数据,也可以向其他计算机发送数据。 学习 socket,也就是学习计算机之间... ...
Socket programming is the process that builds a communication channel between the server and the client using sockets. In the following example code, the client starts a contact with the server, and the server is set up to accept the client connections. Let us understand the server and client...
