What is the functions of zambie process?..

Answer / sandeep patra

guys, we can think of zombie process as a GHOST. when a
person (having some unfinished business on earth) dies they
become ghost, means they are dead but they have there
existence on this earth. Just like that if a process died
but it's existence remains in the process entry table then
that process became Zombie.

now who is going to clean this mess?
so it is the work of the parent process to clean this thing
by waiting on the child process.
if the parent process don't clean up this mess then it would
be the work of operating system to release these resources
when process entry table would be looked up again

Regards,
Sandy :)

What is the functions of zambie process?..

Answer / guest


When a process ends, all of the memory and resources
associated with it are deallocated so they can be used by
other processes. However, the process's entry in the
process table remains. The parent can read the child's exit
status by executing the wait system call, at which stage
the zombie is removed. The wait call may be executed in
sequential code, but it is commonly executed in a handler
for the SIGCHLD signal, which the parent is sent whenever a
child has died.

After the zombie is removed, its process ID and entry in
the process table can then be reused. However, if a parent
fails to call wait, the zombie will be left in the process
table. In some situations this may be desirable, for
example if the parent creates another child process it
ensures that it will not be allocated the same process ID.
