Two problems when I am writing my own shell

Hi, guys:

I am writing my own shell using c. I meet with two problems.

First, when I use tcsetpgrp system call to move a background job to foreground, when this job finishes, my shell program also exit. What is the problem for that?

Second, when I use signal , if the child has its own group, it cannot receive any keyboard signal such as control ^c? I want the child can receive it ,and also has its own group.

Please give me some suggestions.


Thanks

The group is what controls what terminal signals what things, so a separate group naturally wouldn't be under your terminal's control.

As for your other questions, I can't see your code from here, please post it.
