While you said Linux in particular you should be aware that this differs 
considerably from platform to platform as how to do this...

Unix programming faq is a good place to start for this sort of queries
http://www.whitefang.com/unix/faq_2.html#SEC17

There is a gnome library 
http://www.gnome.org/applist/view.phtml?name=LibGTop
Which is an attempt to be a cross platform interface for this sort of 
issue.

I would recommend one of those two approaches, If that still does not 
appeal to you then you can look at the /proc file system. A simple ls 
shows you all the running processes, each dir is a process. Check out the 
source to numerous programs for exact parsing details. Again libgtop is 
probably a good place to start.
