So the answer here is that I have to open "/dev/tty" each time I call it rather than reference my already-open "STDOUT"?

Hmmm....I'm disappointed that I need to open another file handle and can't get the rows & columns associated with my already open FH, "STDOUT", directly...

As for using 'Term::ReadKey', I thought of using something along those lines (or a Curses func), but wanted something that was minimal overhead, as this was called every loop, and portability isn't a major consideration, considering the nature of the program this is being used in is showing linux process and mounted-dev I/O.

If I look at /proc/$$/fd/1, I see a softlink to /dev/pts/1 (i.e. a character, tty type device). Indeed, if I use your 2nd prog and substitute in "/dev/pts/1" instead of "/dev/tty", I get the same result (ie. it works).

Shouldn't STDIN, STDOUT map to fd[0], fd1 => /dev/pts/1 on some level?

I.e. Shouldn't I be able to use some mapping function on STDOUT to get a file descriptor that's suitable for ioctl?
