Despite a tiny setback, I managed to regraded your Lab 4. Grades have been sent to your SoC email account (with @comp.nus.edu.sg address) which you can read by logging into sunfire and run mutt or pine, or by logging into SoC webmail.
One more common error emerges from this regrading. I noticed many of you call either wait() or waitpid() without specifying the PID of the process you are waiting for (in the case of foreground process). This can cause a problem, as any of the previously running background process can interrupt the wait.
Prof Ooi, I didn’t receive any email :(
Could you resend it to me? Thank you.
I’ve just received it, thank you.
