The <STRONG>getyx</STRONG> macro places the current cursor position of the given window
in the two integer variables <EM>y</EM> and <EM>x</EM>.
- If <EM>win</EM> is a subwindow, the <STRONG>getparyx</STRONG> macro places the beginning coordi-
- nates of the subwindow relative to the parent window into two integer
- variables <EM>y</EM> and <EM>x</EM>. Otherwise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.

Besides the problem of opaque structures, the data stored in like-named
members may not have like-values in different implementations. For
example, the WINDOW._maxx and WINDOW._maxy values in ncurses have (at
- least since release 1.8.1) differed by one from some other implementa-
- tions. The difference is hidden by means of the macro <STRONG>getmaxyx</STRONG>.
