C++ TerminateProcess function

I've been searching examples for the Win32 API C++ function TerminateProcess() but couldn't find any.

I'm not that familiar with the Win32 API in general and so I wanted to ask if someone here who is better in it than me could show me an example for,

• Retrieving a process handle by its PID required to terminate it and then call TerminateProcess with it.

If you aren't familiar with C++ a C# equivalent would help too.
