       and window coordinates


</PRE>
<H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>

       <STRONG>void</STRONG> <STRONG>getyx(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>
       <STRONG>void</STRONG> <STRONG>getparyx(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>
       <STRONG>void</STRONG> <STRONG>getbegyx(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>
       <STRONG>void</STRONG> <STRONG>getmaxyx(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>


</PRE>
<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       The <STRONG>getyx</STRONG> macro places the current cursor position of  the
       given window in the two integer variables <EM>y</EM> and <EM>x</EM>.

       If  <EM>win</EM>  is  a  subwindow,  the  <STRONG>getparyx</STRONG> macro places the
       beginning coordinates of the  subwindow  relative  to  the
       parent  window into two integer variables <EM>y</EM> and <EM>x</EM>.  Other-
       wise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.

       Like <STRONG>getyx</STRONG>, the <STRONG>getbegyx</STRONG> and  <STRONG>getmaxyx</STRONG>  macros  store  the
       current  beginning  coordinates  and size of the specified
       window.


</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       The return values of these  macros  are  undefined  (i.e.,
       they  should not be used as the right-hand side of assign-
       ment statements).


</PRE>
<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
       All of these interfaces are macros.  A "<STRONG>&amp;</STRONG>" is  not  neces-
       sary before the variables <EM>y</EM> and <EM>x</EM>.


</PRE>
<H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       The  <STRONG>getyx</STRONG>,  <STRONG>getparyx</STRONG>,  <STRONG>getbegyx</STRONG>  and  <STRONG>getmaxyx</STRONG> macros are
       described in the XSI Curses standard, Issue 4.

       This implementation also provides functions <STRONG>getbegx</STRONG>, <STRONG>getb-</STRONG>
       <STRONG>egy</STRONG>,  <STRONG>getcurx</STRONG>, <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>get-</STRONG>
       <STRONG>pary</STRONG> for compatibility with older versions of curses.

       Although X/Open Curses does not address this, many  imple-
       mentations  provide  members  of the WINDOW structure con-
       taining 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  differ-
       ent  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 implementa-
       tions.  The difference is hidden by  means  of  the  macro
       <STRONG>getmaxyx</STRONG>.
