1. How to check health of child process in a process group

Hi gurus,
How do I check the health of all my child processes, forked by my daemon
process.
All the processes are under same process group.

I want to write a monitor utility, which needs to know the state of all the
child processes
in a process group.

The system security does not allow access to 'ps' and 'kill' commands.

So I have do this, using C system calls.

I looked at waitpid(), but can not figure out, if I can use it, or is there
a better way to do this.

TIA
Deepak
