According to the ncurses.h documentation of struct _win_st, _maxx and _maxy are not the size of the window. However, in all my experiments, these coordinates do correlate to the window size. Can someone explain how there would ever be a case were _maxx does not represent window width or _maxy does not represent window height?

~~ fron ncurses.h ~~

NCURSES_SIZE_T _maxy, _maxx; /* maximums of x and y, NOT window size */

ncurses uses _maxx/_maxy consistently as the maximum x and y indices
respectively.  For instance

            for (j = 0; j <= win->_maxx; j++)
                win->_line[line].text[j] = blank;

The actual width and height of the window would be one more than the
maximum indices because they are zero-based.
