#include <stdio.h>
#include <stdlib.h>
#include <signal.h>

int handle (int signo)
{
 printf ("z handle, signo=%d\n",signo);
}

int inv(int n)//float,int 1/0 SIGFPE = 8
{
    return 1/n;
}

int main()
{
    void (*SIGFPE_saved) ();

    SIGFPE_saved = signal (SIGFPE, handle);
    inv(abs(0));
    printf ("po inv\n");
    signal (SIGFPE, SIGFPE_saved);
    return 0;
}

Co zrobić aby w kólko nie wywoływał handle() ?
