how to implement suspended job handling of a shell using c


in my shell i need to handle suspended job
as if type Ctrl z, the current job is suspended
for example:
[type in your command ]$ cat
^C

then cat is suspended
and the command can be "cat | cat"

i what to get some ideas of how to do it

and the other question, if the parent process is suspended, will the child process also be suspended together?

You suspend a process by sending a specific signal to it. To get the most out of your class assignment, do this at the command line:
Code:
man 2 kill
man 7 signal
And since this is a class assignment, the best way to answer your final question is:

Try it!

Hope this helps.
