How can I check the CPU usage of processor ?

How can I do for Checking the CPU usage of the processor every 100 microseconds ?
I would like to have the % of cpu usage (like the task manager) and I don't know how I can found it !

This can be done using the PDH (Performance Data Helper) DLL, but using it once every 100 usec might put a large load on the CPU itself.

The following routines can help you get started, along with the "perfmon" program in your Win 2000 or WinNT system.
PdhOpenQuery()
PdhCollectQueryData()
PdhGetFormattedCounterValue()

Good luck!
