Subject: runqueue length

Hi,

I am working on a run time threading library in which I want to
interact with the kernel to find out global system utilization
(especially in SMPs).

My question is: Is there a way to find out from an application that how
many active threads are there in OS? By active, I mean ready to run AND
already running (both separately reported or may be one number).
Similarly a number for how many threads are there in wait queues
(blocked on I/O or waiting for an event or a signal). A program might
have multiple threads. This information is useful for runtime library developers, because they can tune their threads and other scheduling.  accordingly.

Thanks for your time,

-Khubaib
