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

SYNOPSIS
       #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);

DESCRIPTION
       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  subwin-
       dow  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.

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

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

PORTABILITY
       The getyx, getparyx, getbegyx and getmaxyx macros are described in the  XSI  Curses  stan-
       dard, 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  WIN-
       DOW._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.
