Hi,
How can I retrieve the performance information
information of process during runtime ?
I know PSAPI can provide some information like memory.
But I want to know CPU information, just like
performance monitor, where CPU%, CPU time can be
shown.
Thanks in advance.

Hello,
The WIN32 API function GetProcessTimes gives you the
CPU time spent by a process in user mode and kernel
mode. For finding the %CPU time, you probably have to
use native API function NtQuerySystemInformation with
information class 5. This returns you various
statistics about all the processes running in the
system. By performing arithmatic calculations on CPU
times of all the processes you can find out %CPU
usage.
