问题描述
我创建了一个TCP套接字而没有关于端口号绑定到[socket.sin_port = 0。但是后来，如果我想打印客户端的端口号，我该怎么做呢？客户机C应用程序（在Linux上）创造了许多客户当中去连接到服务器。要调试问题，我捕捉空灵的流量。我想打印在日志中的端口号，而问题的出现等等空灵的过滤变得容易。
I create a TCP socket without bothering about the port number to bind to [socket.sin_port = 0]. However later on if I want to print the port number of client how do I do that? The client C application (on Linux) creates many clients which get connected to server. To debug issues I capture the traffic on ethereal. I thought of printing the port number in logs while issue arises so that filtering on ethereal becomes easy.
任何帮助将是AP preciated。
Any help would be appreciated.

推荐答案
使用的getsockname（）调用连接成功后获得套接字地址和端口。
Use the getsockname() call to get the socket address and port after a successful connection.
编辑：正确的方法名。有时候，我不能从一个窗口复制一个简单的词来喽！
correct method name. Sometimes I can't copy a simple word from one window to another!
