Get Process List with their current CPU utilization percentage

For a Win32 C++ console application, I need to be able to enumerate the list of processes and get a CPU utilization percentage for each process, similar to what appears in the task manager.

I can't use .NET
I can't use Delphi (for some reason so many examples are for delphi)
I can only use Win32 and C++.

How do I achieve that?

You can take this program from MSDN:

This is a Win32 console application.

Add GetProcessTimes to the previous example:

I think everything's explained in this article:

One thing that's unclear about GetProcessTimes is the timespan. This seems like a statistical tool that can tell me,

"your application has been up for 5 weeks"
"your application used 1 week of CPU time"

Therefore I can deduce that overall, my process took 20% of the CPU during its lifetime.

however, what if I need a more "real time" monitoring? what if an app that took 1% over two weeks suddenly peaks to 99% CPU? how will I catch that in real time like TASK MANAGER does? This is really what I'm interested in, not over-time statistics but a rather "current" snapshot, based on the last x seconds.

Is there anything like that I can already use? or do I simply have to track the process for those X seconds and, monitor the elapsed time, and "sample" its CPU usage myself using deltas?

I mean, I can do this myself, but was wondering whether there's a ready made value I can pick up somewhere.

Read the article. There is the code you need. Download it. CpuUsage class has GetUsage method. Take a look.
