CPU Utilization

Does anyone out there know of any ways to determine how the CPU is being
utilized under Neutrino? For instance, how much time a particular
process/thread gets over time? I suppose that if I could ‘eavesdrop’ on the
scheduler, I could determine this, but I don’t know how to do that either.
sin and sac were kind of useful under QNX4, but I see they are missing in
Neutrino… I suppose it brings me to the brink of the quagmire around how
you determine this without affecting CPU utilization, but I will leave this
to the PHD’s.

Thanks

Checkout the ClockId() and ClockTime() functions.
