Environment is Active Perl 5.8.8 on Windows.
Does anyone know if there is a keystroke combo that will result in a
SIG{QUIT} in the currently running Perl app?
I know that SIG{INT} and SIG{BREAK} happen on CTRL-C and CTRL-Break.
Thanks,
Barry Brevik

These are the only 2 signals supported by the Win32 API, so there is
no keystroke combo that generate SIGQUIT.

I get a QUIT on either Ctrl-Break or CTRL-ScrollLock (but not on my
remapped CapsLock key - only on the real ones) and INT on Ctrl-C.
Not sure if that's of any use. I'm using tcsh though. In cmd.exe,
I also get an INT on Ctrl-X.

My bad - I had tcsh running under cmd.exe for that scenario.
That's strange in itself - tcsh uses ^X for command completion
stuff. Maybe it's cmd.exe doing something with just children ????

Oh, and anyways, SIGQUIT has been remapped on Windows to be the same as
SIGBREAK, so even if there was a keystroke that generated it, you still
wouldn't be able to distinguish it from SIGBREAK. $SIG{BREAK} and
$SIG{QUIT} are aliases for the same signal handler on Windows.
