63 </PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
64 The <STRONG>getyx</STRONG> macro places the current cursor position of the given window
65 in the two integer variables <EM>y</EM> and <EM>x</EM>.
67 If <EM>win</EM> is a subwindow, the <STRONG>getparyx</STRONG> macro places the beginning
68 coordinates of the subwindow relative to the parent window into two
69 integer variables <EM>y</EM> and <EM>x</EM>. Otherwise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.
71 Like <STRONG>getyx</STRONG>, the <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> macros store the current
72 beginning coordinates and size of the specified window.
75 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
76 The return values of these macros are undefined (i.e., they should not
77 be used as the right-hand side of assignment statements).
80 </PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
81 All of these interfaces are macros. A "&" is not necessary before the
82 variables <EM>y</EM> and <EM>x</EM>.
85 </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
86 The <STRONG>getyx</STRONG>, <STRONG>getparyx</STRONG>, <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> macros are described in
87 X/Open Curses, Issue 4.
89 This implementation also provides functions <STRONG>getbegx</STRONG>, <STRONG>getbegy</STRONG>, <STRONG>getcurx</STRONG>,
90 <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>getpary</STRONG> for compatibility with
91 older versions of <EM>curses</EM>; see <STRONG><A HREF="curs_legacy.3x.html">curs_legacy(3x)</A></STRONG>.
93 Although X/Open Curses does not address this, many implementations
94 provide members of the <STRONG>WINDOW</STRONG> structure containing values corresponding
95 to these macros. For best portability, do not rely on using the data
96 in <STRONG>WINDOW</STRONG>, since some implementations make <STRONG>WINDOW</STRONG> opaque (do not allow
97 direct use of its members).
99 Besides the problem of opaque structures, the data stored in like-named
100 members may not have like-values in different implementations. For
101 example, the <STRONG>WINDOW._maxx</STRONG> and <STRONG>WINDOW._maxy</STRONG> values in <EM>ncurses</EM> have (at
102 least since release 1.8.1) differed by one from some other
103 implementations. The difference is hidden by means of the macro
104 <STRONG>getmaxyx</STRONG>.
