child process statistics

[Dean Herington]

Does anyone know how to get the process statistics (cputime, page faults,
etc.) for a child process?  When the child process has terminated, before
doing getAnyProcessStatus on it, I'd like to get its statistics.

Browsing the libraries documentation didn't turn anything up.  I couldn't
even find what I want at the Unix level among man pages.  (I'm happy to
write some FFI code to access system routines if I can locate the right
ones.)
