I'm new to this, but it seems like rt_msghdr->rtm_index in macOS is the interface index I want to get the actual interface used by each route, just like netstat -nr

I used Go before and it did the same thing https://cs.opensource.google/go/x/net/+/master:route/route_classic.go;drc=d23d9bc549229fd1a9d375dc91141fcf1385d257;l=47
