Restart a computer using function pointers in C

Question

I was learning about function pointers in C when I came across a program that restarts the computer upon execution.

void (*f) (void);
f=(void (*)(void) MK_FP(0xF         


        

Answer 1

The code is attempting to jump to the address where x86 CPUs start executing at power-on, aka the "Power On Reset Vector" (source).
