DESCRIPTION</H2><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>.
</PRE>
-<H2>
RETURN VALUE</H2><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>&</STRONG>" is not neces-
sary before the variables <EM>y</EM> and <EM>x</EM>.

PORTABILITY</H2><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 <STRONG>getbegx</STRONG>, <STRONG>getbegy</STRONG>,
- <STRONG>getcurx</STRONG>, <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>getpary</STRONG>
- for compatibility with older versions of curses.
+ 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>.
