I think there isn't explicitly any process running after netctl is done configuring the network configuration. So you should either get more specific about the kind of information you want, so whether you are talking about network state or netctl's opinion about it (not that these are likely to diverge, but there's my point)...
Uhm... a glance into netctl's source just revealed it's a bash script. You'll need exec anyway.
wait. so: https://github.com/joukewitteveen/netctl/blob/master/src/lib/globals#L6 char *statefile = getenv("NETCTL_STATE_FILE"); FILE *f; if(!statefile) statefile = "/var/lib/netctl/netctl.state"; // from /usr/lib/network/globals f = fopen(statefile, "r"); if(f) { // parse whatever you find there... } but... I think the point in running netctl is that running it would update said state file. So, the state file might be there and all. That's how I believe these diverge. You'd have to analyze what netctl does there and replicate that in c, but ... no really, use exec(). cheers! mar77i
