I also need this functionality, as least insofar as the CPU usage
fields are concerned.
Generally, there is no way to get this information for another
process, unless it's your child process, and it has terminated, or
unless it is for yourself.
The most correct approach is to ask the other process to make the
call, and then tell you, simce time is not really accounted for all
your threads until you make the call (the BSD getrusage() output is
more or less synthetic).
