How to determine CPU usage using WINAPI?

Question

C++ / C#

Good day to all! The task is to write an analogue of the task manager with the ability to obtain information about the process (name, id, priority, CPU usage by a specific process, memory occupied by it). Can't get CPU usage at all. Is it possible to get such information using WinAPI?

Answer 1

GetProcessTimes to get the CPU time spent on a particular process
GetSystemTimes to get the total CPU usage info generally
call them twice with a delay of one second, find the difference and divide by the amount of elapsed time. something like this.
