If you're on a Linux system you might be far better accessing
the /proc/$PID/stat files directly. The values you'd find therein
are documented:
http://www.die.net/doc/linux/man/man5/proc.5.html
(among other places).
Of course you could write you code to look for file and fall back
to use the 'ps' command if it fails. In addition you can supply
arguments to the 'ps' command to limit it to reporting just on the
process(es) in which you are interested ... and to eliminate the
header line and irrelevant columns of output.
