C, kill all processes

Question

I have a project for school and I need some help. I'm working in C and I have a server and a client. In server I make a new process for each client with fork. My question is: if I close the server with CTRL+C, how do I kill all the remaining processes ? Thanks

Answer 1

You can store their pids after they are created and then, when quitting, signal sigterm or sigkill to them.

You can do it through shell - killall is what you are searching for under linux.

You could use threads instead of processes (could you? what do the project details say?) and communicate through variables.
