How do you use the ptrace() call?  We cannot find any documentation for it.
We are trying to use ptrace() to get the process's data and text 
segments, also the proc structure and the user structure.  How do we do 
this using ptrace()?

We'd appreciate if you could include sample code to use ptrace.
Thanks!
