Write a C program that illustrates how an orphan is created.
Program:
#include <stdio.h> main() { int pid ; printf("I'am the original process with PID %d and PPID %d.\n",getpid(),getppid()); pid=fork(); if(pid!=0 ) { printf("I'am the parent with PID %d and PPID %d.\n",getpid(),getppid()); printf("My child's PID is %d\n",pid) ; } else { sleep(4); printf("I'm the child with PID %d and PPID %d.\n",getpid(), getppid()) ; } printf ("PID %d terminates.\n", getpid()) ; }
Output:
guest-glcbIs@ubuntu:~$gcc –o prg18.out prg18.c guest-glcbIs@ubuntu:~$./prg18.out I am the original process with PID2242 and PPID1677. I am the parent with PID2242 and PPID1677 My child’s PID is 2243 PID2243 terminates. $ I am the child with PID2243 and PPID1. PID2243 termanates.
