Thanks for Matthew. I have one more question. I want to obtain cpu usage rate you can see it in TaskManager in windows.
TaskManager shows us a cpu usage per thread. I looked the reference manuals in Web Site but I didn't find it. So How can I obtain that rate value per thread? Thanks for your reply. Have a nice day.
