Reading the route table on FreeBSD

I'm porting an application from Linux to FreeBSD that needs to look at the table of network routes ("route" on Linux or "netstat -r" on FreeBSD).

On Linux, the application simply reads /proc/net/route and /proc/net/inet6_route.

What is the best way to do this programatically on FreeBSD ?

This is documented in the man page route(4). Basically, you read() and write() a PF_ROUTE socket. You can look at the /sbin/route source for an example.
