Confirmed fixed in 15.3 release, thank you.

Yes. Let me fix.

[MBS] CPU use on OS X and Windows

[Michael Diehr]

Related question: How do i get the CPU usage, for the current process only, on 
Cocoa and Win32.

I'd like to get the same value that shows up in Activity Monitor's CPU% column, 
and for windows Task Manager.  I'm only interested in the CPU usage for the 
currently running process.

For Cocoa, I see DarwinVMStatisticsMBS but I'm not clear if that's per-process 
or global?

For Win32, should I use WindowsProcessStatisticsMBS?  Is it per-process or 
global?

Thanks

DarwinVMStatisticsMBS is global.
I think DarwinResourceUsageMBS is for your app.

If you pass ProcessID it's for this process, I think.

Hmm - testing the "Darwin Resource Usage" sample project however, I get "0" for 
System Time used and UserTimeUsed, which doesn't seem very useful for 
calculating real-time CPU usage.   Correction, after a while UserTimeUsed rises 
to 1 and then 2, but it takes about a minute.  Should these perhaps be doubles 
rather than integers?
