c - 如何确定BSD / OS X系统上C语言中的标准网关地址？

我想获取BSD / OS X系统上标准网关的IP地址。

这是一个简单的问题，但是，我很难获得答案。

此帖子： Getting gateway to use for a given ip in ANSI C已经回答了这个问题，但仅适用于非BSD / -OSX系统。

由于在BSD系统上创建Raw套接字很困难，并且没有<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我唯一发现的是有一个名为PF_ROUTE的家庭，它似乎是用于此目的的正确家庭（PF_NETLINK）。我仍然不知道相应的协议。

自从我不知道如何开始以来，到目前为止我还没有真正尝试过。
