DE10-Nano Handling FPGA interrupts

Hello, I'm trying to find info on how to handle an IRQ from FPGA to HPS via f2h_irq0 Interrupt Receiver. For now I don't have a clue. I just found info on how to handle GPIO like KEY0 or KEY1...

Hey thanks!

I should stated that I was working under linux!. I was reading the altera documentation for HWLIB and SoCAL APIs without success.

This is a simple starting program with a strange error: 

#include <stdio.h>
# include "hwlib.h"
# include "alt_interrupt.h"
int main() {
  ALT_STATUS_CODE status;
  status = alt_int_global_init();
  if(status == ALT_E_SUCCESS) printf("exito...");
  return 0;
}

I got this error: 

main.o: In function `main':
C:\Users\nhasbun\Desktop\C/main.c:7: undefined reference to `alt_int_global_init

I guess it's a linker problem on my makefile ?
