       getyx, getparyx, getbegyx, getmaxyx - get curses cursor and window coordinates


       #include <curses.h>

       void getyx(WINDOW *win, int y, int x);
       void getparyx(WINDOW *win, int y, int x);
       void getbegyx(WINDOW *win, int y, int x);
       void getmaxyx(WINDOW *win, int y, int x);


       The  getyx macro places the current cursor position of the given window in the two integer
       variables y and x.

       If win is a subwindow,  the  getparyx  macro  places  the  beginning  coordinates  of  the
       subwindow relative to the parent window into two integer variables y and x.  Otherwise, -1
       is placed into y and x.

       Like getyx, the getbegyx and getmaxyx macros store the current beginning  coordinates  and
       size of the specified window.


       The  return  values  of  these  macros are undefined (i.e., they should not be used as the
       right-hand side of assignment statements).


       All of these interfaces are macros.  A "&" is not necessary before the variables y and x.


       The getyx, getparyx, getbegyx  and  getmaxyx  macros  are  described  in  the  XSI  Curses
       standard, Issue 4.

       This  implementation  also provides functions getbegx, getbegy, getcurx, getcury, getmaxx,
       getmaxy, getparx and getpary for compatibility with older versions of curses.

       Although X/Open Curses does not address this, many implementations provide members of  the
       WINDOW  structure  containing 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  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 implementations.  The difference is hidden by means of the macro getmaxyx.
