java-Socket编程之(tcp/ip) 一、相关概念 1为了能够方便的开发网络应用软件,由美国伯克利大学在Unix上推出了一种应用程序访问通信协议的操作系统调用socket(套接字)。socket的出现,使程序员可以很方便地访问TCP/IP,从而开发各种网络应用的程序。 随着Unix的应用推广,套接字在编写网络软件中得到了极大的普及。后来,套...

Port 0 carries special significance in network programming, particularly in theUnixOS when it comes tosocket programmingwhere the port is used to request system-allocated, dynamic ports. Port 0 is a wildcard port that tells the system to find a suitable port number. Unlike mostport numbers, po...

(4) 每当有客户端连入的时候,我们就还是得调用CreateIoCompletionPort()函数,这里却不是新建立完成端口了,而是把新连入的Socket(也就是前面所谓的设备句柄),与目前的完成端口绑定在一起。 至此,我们其实就已经完成了完成端口的相关部署工作了,嗯,是的,完事了,后面的代码里我们就可以充分享受完成端口带给我们的巨大...
