For fork:ed Gambit process that should not take any console input, how uninitialize stdin & signal handlers? (Possibly only needed to be done for the handler for SIGTSTP.)
Hi, making a strace wrapper app monitor to be run in a fork:ed Gambit process. This process is completely silent and never has any console interaction except for minor output to stdout. In the current setup, when I press ctrl+c, both forked processes respond with getting to the REPL. For the fork:ed process that should not have any console interaction anymore, how do I disable this behavior i.e. how do I shut down signal handlers & stdin for it? (Possibly only needed to be done for the handler for SIGTSTP.) I tried doing (close-port (current-input-port)) but it didn't deliver for this purpose. Kind regards, Mikael

Invoking setsid() on the child as only "console shutdown/detach" action delivered completely for this purpose, resolved. Kind regards 2011/10/29 Mikael <mikael.rcv@gmail.com>
