    curs_getyx(3x)                   Library calls                  curs_getyx(3x)

## 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; see curs_legacy(3x).

           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.
