Hi Matías,

 Yes, there is. But I can only think in a 'brute force' way: you can scan the
/proc file-system.

 Let's say you want to know how many children the X process has. You open
each '/proc/PID/status' and read the 'Ppid' field. If it's equals X, you
count it.

 As I said, it's ugly, but I cannot think in another solution.

 You can try to read the code of 'pstree' program, but I guess it
scans the /proc file-system too.
