Dear system managers,

Dunix 4.0d

I' m looking for a piece of code which , given a Process Id, can print
the percentage of the CPUs and of the RAM the process is using.
I need the some value given by
ps aux
but I would like to do it by C not by shell.

Any suggestion ?

Thanks from Italy,
Emanuele
