  66        The <STRONG>getyx</STRONG> macro places the current cursor position of  the
  67        given window in the two integer variables <EM>y</EM> and <EM>x</EM>.
  68
  69        If  <EM>win</EM>  is  a  subwindow,  the  <STRONG>getparyx</STRONG> macro places the
  70        beginning coordinates of the  subwindow  relative  to  the
  71        parent  window into two integer variables <EM>y</EM> and <EM>x</EM>.  Other-
  72        wise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.
  73
  74        Like <STRONG>getyx</STRONG>, the <STRONG>getbegyx</STRONG> and  <STRONG>getmaxyx</STRONG>  macros  store  the
  75        current  beginning  coordinates  and size of the specified
  76        window.

  81        The return values of these  macros  are  undefined  (i.e.,
  82        they  should not be used as the right-hand side of assign-
  83        ment statements).
  84
  85
  86 </PRE>
  87 <H2><a name="h2-NOTES">NOTES</a></H2><PRE>
  88        All of these interfaces are macros.  A "<STRONG>&amp;</STRONG>" is  not  neces-
  89        sary before the variables <EM>y</EM> and <EM>x</EM>.

  93 <H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
  94        The  <STRONG>getyx</STRONG>,  <STRONG>getparyx</STRONG>,  <STRONG>getbegyx</STRONG>  and  <STRONG>getmaxyx</STRONG> macros are
  95        described in the XSI Curses standard, Issue 4.
  96
  97        This implementation also provides functions <STRONG>getbegx</STRONG>, <STRONG>getb-</STRONG>
  98        <STRONG>egy</STRONG>,  <STRONG>getcurx</STRONG>, <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>get-</STRONG>
  99        <STRONG>pary</STRONG> for compatibility with older versions of curses.
 100
 101        Although X/Open Curses does not address this, many  imple-
 102        mentations  provide  members  of the WINDOW structure con-
 103        taining values corresponding to these  macros.   For  best
 104        portability,  do  not  rely  on  using the data in WINDOW,
 105        since some implementations  make  WINDOW  opaque  (do  not
 106        allow direct use of its members).
 107
 108        Besides  the problem of opaque structures, the data stored
 109        in like-named members may not have like-values in  differ-
 110        ent  implementations.   For  example, the WINDOW._maxx and
 111        WINDOW._maxy  values  in  ncurses  have  (at  least  since
 112        release 1.8.1) differed by one from some other implementa-
 113        tions.  The difference is hidden by  means  of  the  macro
 114        <STRONG>getmaxyx</STRONG>.
