Get the current function used to handle control+zby exodist (Monk) |

exodist has asked for the wisdom of the Perl Monks concerning the following question:
Hello monks, I am writing a module that gets input in raw mode and interprets the special chartacters such as escape, insert, F1-F12, and control keys such as control+a-z.
Currently I have actions occur when certain keys are pressed. I want these to be overridable. For control+c I bound it like so: '<CONTROL+C>' => sub { exit(0) }; I need to do something similar for control+z, to make it background the process. At first I tried this: '<CONTROL+Z>' => $SIG{INT}; But it seems this is empty unless set to something new. I need to know of a way to do this if it is possible. -------------------------------------- I would rather take 30 minutes to re-invent the wheel then take 30 days to learn how to use someone else's. Before pestering me about my re-invention prepare to defend yourself with a way of learning how to use the wheel in less time than it takes for me to make one, one that I might add is specialized to my specific task!
