Sorry, should have posted a link:

https://metacpan.org/pod/release/KXJ/Win32-Process-CpuUsage-0.02/lib/Win32/Process/CpuUsage.pm

For some reason one cannot find this via metacpan's search functionality.

Is there a chance to intercept the ouptput of the function GetProcessCpuUsage, e.g., by manipulating the tty, when called by a program which uses/requiress this module?
