A process of father create (fork) a son and will sleep 90 seconds..After this, son process create a grandchild and will sleep 60 seconds..Grandchild process will sleep for 30 seconds..After sleep,each process must write a message about which process is and what is the PID..

Can you tell me more about your application? What's the purpose of just forking and sleeping?

it must be a program which has written in C (gcc)..This program will use the fork,sleep,wait and write to do the process which i refer up..it must be only about what i refer up,i dont want a big program with many details..
