Thats almost certainly because ping never reads its input.
In that case you'll need to send a kill signal to the process and
to do that you need to find the process ID. I'm not sure if
popen() provides access to the PID but if not you could
either search for it (this might be too slow) or just drop
down to use fork rather than popen, as fork will return
the PID.
