They provided an example of how `wcon_setcolor` is implemented using Win32 API
calls, including `SetConsoleTextAttribute`. Whether that's agreeing with you or
not, I'd rather not guess.

I'm not disputing that TUI and non-TUI programs are different. I was trying to
provide evidence in reply to """I stand by my statement that "curses programs
do not normally use stdin, stdout, or stderr", but am ready to be corrected and
learn.""".
I thought this exercise would convince you that the program (the curses part of
it, to be precise) is not communicating with the terminal window via any other
channels than std{in,out}. I was hoping to demonstrate that by showing that
`cat`, not a curses program, can create the same terminal output as a curses
program.
Which part of the argument do you disagree with, if any?
