What is the most correct way to restart Linux from within your program?

Question

linux

In Lazarus, I use this code:
FpKill(1, SIGINT);
My program runs with system privileges, reloading looks correct on the outside.
Am I doing everything right?

Answer 1

and can run a standard command?
reboot

Answer 2

You can send a signal to init and the system will automatically reboot. However, using standard tools (shutdown, reboot) it is easier to do this.
