I have 2 programs (written by me). The first one called “MAN” will invoke “D” (the second one) which is a process that will run in background until terminated in some ways.

I would like to terminate MAN without terminating D.

I try to terminate MAN using ctrl + c and it terminates man correctly (I intercepted the sigint signal), now I want that D keeps running, however when MAN receives CTRL + C, D receive it too.

How to handle this situation? It’s important that I would like to keep the possibility to run only D and terminate with CTRL + C. The problem comes when I run it through MAN, I don’t want to terminate it with CTRL + C which should reach MAN only.

Any suggestion?

    The child process (D) should disassociate from the controlling terminal by calling setsid(2).
