sigaction for SIGINT, SA_RESETHAND

Is there a way to handle SIGINT only 2 times and return it to default using SA_RESETHAND? We must use sigaction, and make our handler reinstall by itself 2 times and then install flags to resethand. But there's a question: how to reinstall my handler only 2 times and how to use RESETHAND in this situation? n-1?

void sig_int(int sig)
{
    printf(" -> Ctrl-C\n");
    struct sigaction act;
    act.sa_handler = SIG_DFL;

    if(sigaction(SIGINT, &act, NULL) < 0)
    {
        exit(-1);
    }

}

int main()
{
    struct sigaction act;
    act.sa_handler = sig_int;

    if(sigaction(SIGINT, &act, NULL) < 0)
    {
        exit(-1);
    }

    while(1)
    {
        sleep(1);
    }

    return 0;   
}
