PORTABILITY

-       The  getyx,  getparyx, getbegyx and getmaxyx functions are
+       The  getyx,  getparyx,  getbegyx  and  getmaxyx macros are
        described in the XSI Curses standard, Issue 4.
 
-       This  implementation  also  provides   getbegx,   getbegy,
-       getcurx,  getcury,  getmaxx,  getmaxy, getparx and getpary
-       for compatibility with older versions of curses.
+       This implementation also provides functions getbegx, getb-
+       egy,  getcurx, getcury, getmaxx, getmaxy, getparx and get-
+       pary for compatibility with older versions of curses.
+
+       Although X/Open Curses does not address this, many  imple-
+       mentations  provide  members  of the WINDOW structure con-
+       taining values corresponding to these  macros.   For  best
+       portability,  do  not  rely  on  using the data in WINDOW,
+       since some implementations  make  WINDOW  opaque  (do  not
+       allow direct use of its members).
+
+       Besides  the problem of opaque structures, the data stored
+       in like-named members may not have like-values in  differ-
+       ent  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
+       getmaxyx.
