I googled for you

> 1. how can window resizing information be passed on to the running perl process (such as sigwinch) then

> 2. how do I resize my output parameters to match.

Without knowing your code, I'd say try to access the settings in the callback

see also To find out console line size in char.s .

you may also want to give Curses a try.
