Replying to myself...

So after eyeballing the ccl sources, I finally got to this, which seems
(format t "winsize: ~S~%"
(rlet ((winsize :winsize))
(let ((result (ccl::int-errno-call
(#_ioctl (ccl::stream-device *standard-output* :output)
#$TIOCGWINSZ :address winsize))))
(if (zerop result)
(pref winsize :winsize.ws_col)
(unless (= result #$ENOTTY)
Am I correct in assuming that :address is needed to specify the type of
the next argument because ioctl is a variadic function in C ? I would
just like confirmation that I'm doing things the right way now...
Resistance is futile. You will be jazzimilated.
