Your best bet is to use popen(3C) on the netstat command and parse the
output yourself. If you're wandering into getkerninfo, I think you're
in a really rough neighborhood. That gets into kernel implementation
details, and if you make your program dependent on the undocumented
parts of your OS kernel, then your program may fail unexpectedly the
next time the system is upgraded or patched.
