<strong>Lab</strong> 3: Situations with Wait<br />
• Child exits before the parent and:<br />
– parent will exit without calling wait().<br />
Child<br />
exit(0)<br />
keep the exit value<br />
Destroy the exit value!<br />
Parent<br />
exec(Child)<br />
exit(0)<br />
You should keep child’s exit value until the parent exits<br />
(since the child doesn’t know if the parent calls wait() later on)<br />
