Task: Create Process

Enter the labs/lab-06/tasks/create-process/ directory, run make skels, open the support/src folder and go through the practice items below.

Use the tests/checker.sh script to check your solutions.

./checker.sh
exit_code22 ...................... passed ... 50
second_fork ...................... passed ... 50
100 / 100

1. Change the return value of the child process to 22 so that the value displayed by the parent is changed.

2. Create a child process of the newly created child.

Use a similar logic and a similar set of prints to those in the support code. Take a look at the printed PIDs. Make sure the PPID of the “grandchild” is the PID of the child, whose PPID is, in turn, the PID of the parent.
