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

SYNOPSIS
     #include 

     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  begin-
     ning  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 win-
     dow.

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 standard, Issue 4.

     This implementation also provides  functions  getbegx,  get-
     begy,  getcurx,  getcury, getmaxx, getmaxy, getparx and get-
     pary for compatibility with older versions of curses.

     Although X/Open Curses does not address this, many implemen-
     tations  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 imple-
     mentations 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.
