Limit CPU Usage in C++

Question

Is there a way to limit CPU usage in C++?

I mean can I write a program which takes input %CPU to be used and it uses maximum that much amount of CPU.

I basically want to add the functionality of cpulimit command internally in the program.

If there is, how to do it ?

Edits:

Environment: Linux (debian) with gcc 6.1. It should support as many arbitrary numbers as possible. i.e a range of 1% - 100% . If the OS cannot do, an error can be logged and the nearest value to it can be used or any other solution that is recommended when the OS restricts that number.

Answer 1

Use getrusage(), see Linux commands to detect the computer resource usage of a program

And when you check, and you've used however many milliseconds of runtime you want, use nanosleep() to sleep a few milliseconds. Adjust percentages to match your requirements.
