这段代码的流程也很简单,就是分配一个新的socket对象,这个socket的新对象当有新连接进来时,用于与客户端进行连接,然后调用inet_accept(): 1int inet_accept(struct socket *sock, struct socket *newsock, int flags,2bool kern)3{4struct sock *sk1 = sock->sk;5int err = -EINVAL;6struct sock *sk2 ...

使用 Socket 类的 close()方法关闭连接。 我们的第一个 TCP 应用程序叫 TCPEchoClient.java,这是一个通过 TCP 协议与回馈服 务器(echo server )进行通信的客户端。回馈服务器的功能只是简单地将收到的信息返回给 客户端。在这个程序中,要回馈的字符串以命令行参数的型式传递给我们的客户端。很多系 统都包含...
