Re^5: Invalid value for shared scalar

Hm. All I can tell you is that it works for me on my system.

If you are on Win32, post the output from Perl -V and I'll see if I can isolate the difference.

If you are on some flavour of *nix, then maybe ^C doesn't generate a SIGINT? You'll have to talk to someone with knowledge of your platform to resolve this issue.

I should add that using an interupt handler this way is not really an "architected" solution, just a simple mechanism that allowed me to produce a reasonably clean demonstration without getting into the nitty gritty of a full fledged application.

fair enough. Its just a standard debian install. I will do further research. Thanks so much for all the help.	[reply]

One further thought. Id the problem occuring in the code I posted, or in a modification or adaption of it? To my knowledge, signal handlers will only work in the main thread, not in a subthread. If you have moved the signal handler into a subthread, that might explain the difference? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Produces the same thing with your code exactly, so must just be a difference in compile options or something like that. Thanks again.	[reply]
