curs_getyx (3X)                                                                                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.

       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 likevalues
       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.
