<d4ryus>hi! I have a problem with SIGACTION, it returns an 'Invalid argument' error when i try to set a handler for SIGSTOP. Other signals like SIGUSR1 or SIGCONT work. Any Ideas? <d4ryus>to reproduce (guile 2.2.6 on Archlinux): (sigaction SIGSTOP (lambda (sig) (display "Oh no!"))) <weinholt>d4ryus, from signal(7): "The signals SIGKILL and SIGSTOP cannot be caught, blocked, or ignored." <d4ryus>weinholt: oh well... Thank you very much <jcowan>The whole point of SIGSTOP is that it allows you to stop a process in order to examine it, just as the point of SIGKILL is that it allows you to kill a process, no matter what the process allows. SIGTSTP is the one a process might want to intercept, as that's sent by ^Z. ***slyfox_ is now known as slyfox
