int socket(int domain, int type, int protocol);//成功返回套接字描述符.出错返回-1 这一步事实上是确定通信特征,各个域domain有自己的格式表示地址,以AF_开头(address family);type确定套接字类型,如数据报、字节流;协议protocol对同一个域和套接字类型支持的多个协议进行选择,通常为0,即按给定的域和套接...

The socketsAPIuses the TCP_NODELAY socket option to disable the Nagle algorithm. Here we'll show another example that's easier to demonstrate-typing one of the terminal's special function keys during an interactive login. The function keys normally generate multiple bytes of data, often beginning...
