Hi,
POSIX 2024 added these two functions in termios.h, tcgetwinsize and
tcsetwinsize. They get and set the terminal size respectively.
As far as I can tell only NetBSD has them implemented [1]. They seem
pretty useful and are easy to implement. I've attached two files that
should work on Linux and BSDs (and any other system with ioctl,
TIOCGWINSZ, TIOCSWINSZ).
Any thoughts on adding them? Windows should be able to support them
too [2]. I just need to define 'struct winsize' in termios.h.
