You might miss the second of interest, since the
actual delay between invocations of tprt will be
longer than one second in many cases, due to
bash overhead, process spawning overhead, etc. I'd
suggest putting a "usleep(500000);" in tprt.c and
omitting the "sleep 1" from the shellscript. Yeah,
you get a lot of duplicate seconds, but better safe
than sorry. Especially in such a critical piece of
code!
