从套接字获取地址族.的Linux [英] Get address family from socket. Linux

问题描述

我想为Linux Socket API编写一个C ++包装器.在socket()中，请求地址族(AF).我不想再次要求在connect()签名中使用AF，因为它已在套接字的构造函数中给出.那么如何从现有的插槽中获取AF?

I want to write a C++ wrapper for the Linux Socket API. In the socket() ctor the adress family (AF) is requested. I dont want to require the AF in the connect() signature again, becuase it has been already given in the constructor of socket. So how do I get the AF from an existing socket?
