Is there any User Space API/way for me (a process) to get the
system/user CPU usage of one of my currently running child process? Am
looking for a portable solution...not sure if there is any

There is a way to get the times for all children:
getrusage(RUSAGE_CHILDREN, &usage);
You can double-fork to get the info for a specific subprocess.
/proc is, as you probably noticed, not portable.
