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 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.

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, 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.
