A zombie process or defunct process is a process that has
completed execution but still has an entry in the process
table, this entry being still needed to allow the process
that started the zombie process to read its exit status.
The term zombie process derives from the common definition
of zombie—an undead person. In the term's colorful
metaphor, the child process has died but has not yet been
reaped.

When i run a programm of orphan process. Instead of getting child's parent (ppid)=1 ..i get 1400 and it varies as per system. How can i findthe right soluion??? My pgm: #include # include int main() { int pid; pid=fork(); if(pid < 0) {exit(-1);} else if(pid==0) { printf("Child Process is Sleeping ..."); sleep(10); printf("Orphan Child's Parent ID : %u ",getppid()); } else { printf("Parent Process Completed ... %u ",getpid()); exit(0); } return 0; } Output:
