Try-catch-like Behaviour with Skipping Critical Code in C

Question

ANSI C equivalent of try/catch?

Is there a way to skip critical code ? More or less like try-catch in modern programming languages. Just now I'm using this technique to spot errors:

bindSignals();
{
    signal(SIGFPE, sigint_handler);
    // ...
}

int main(void)
{
    bindsignals();
    int a = 1 / 0; // division by zero, I want to skip it
    return 0;
}

The problem is if I don't exit the program in the handler I get the very same error again and again. If possible I would like to avoid goto. I also heard about "longjump" or something. Is it worth to (learn to) use ?

I'm done. That's how my code looks like now. Almost like Java and C#.

#include <setjmp.h>

jmp_buf jumper;

#define try           if (setjmp(jumper) == 0)
#define catch         else
#define skip_to_catch longjmp(jumper, 0)

static void sigint_handler(int sig)
{
    skip_to_catch;
}

int main(void)
{
    // init error handling once at the beginning
    signal(SIGFPE,  sigint_handler);

    try
    {
        int a = 1 / 0;
    }
    catch
    {
        printf("hello error\n");
    }
    return 0;
}
