564 * varies from release to release of the OS. In order to maintain

575 * To compute sizeof(struct proc), we need the addresses of two proc
576 * structures and their corresponding pids. Given the pids, we can use

578 * proc[] array. By dividing the distance between the pointers by the

596 * pointer. If process 0 has no children, we simply give up and do not
