So that the shell will not be hanged. ---------------------------- revision 1.4 date: 2015/02/25 17:29:31; author: root; state: Exp; lines: +10 -0 Here i have declared a int variable n which have unique values for both parent and child process.

Else it is a parent process. ---------------------------- revision 1.2 date: 2015/02/25 17:17:08; author: root; state: Exp; lines: +3 -0 Here i have declared a variable f_ret whose datatype is pid_t After that i have created a child process using fork() Here fork is returning two values which will be copy on right in the f_ret One value is for parent process and that value will be the PID of the child process. Another value will be 0 when fork() is executed by the child process ---------------------------- revision 1.1 date: 2015/02/25 17:14:14; author: root; state: Exp; Initial revision =============================================================================
