That's exactly what I'm looking for, thanks.
After catching the interrupt and doing whatever I need to do, I want to
allow the process to be stopped as normal. Is this the right way?
import signal, os
def handler(signalnum, stackframe):
print "Received signal %d" % signalnum
os.kill(os.getpid(), signal.SIGSTOP) # Hit myself with a brick.
signal.signal(signal.SIGTSTP, handler)
It seems to work for me (on Linux), but is it the right way?
