How To Prevent Sigint In Child Process From Propagating To And Killing Parent Process?

I've recently learned how to do the whole fork/exec/wait thing and ended up writing some code that looked like this stripped down: #include #include

Solution 1:

you can either catch the SIGINT or write a signal handler. use the code below:

signal(SIGINT, sig_handler);
void sig_handler(int signo)
{
  if (signo == SIGINT)
    printf("received SIGINT\n");
}
