How to kill a child.

This note demonstrates how to spawn and kill a child. For the sake of simplicity, I chose C instead of real life for the example.

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
 
int main()
{
    pid_t pid = fork();
    if (pid == 0) {
        printf("Killing the child using with next line.");
        _exit(0);
    } else if (pid > 0) {
        printf("While we're at it, might as well kill the parent as well");
        exit(0);
    }
}
