63 The <STRONG>getyx</STRONG> macro places the current cursor position of the given window
64 in the two integer variables <EM>y</EM> and <EM>x</EM>.
66 If <EM>win</EM> is a subwindow, the <STRONG>getparyx</STRONG> macro places the beginning coordi-
67 nates of the subwindow relative to the parent window into two integer
68 variables <EM>y</EM> and <EM>x</EM>. Otherwise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.
70 Like <STRONG>getyx</STRONG>, the <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> macros store the current begin-
71 ning coordinates and size of the specified window.
74 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
75 The return values of these macros are undefined (i.e., they should not
76 be used as the right-hand side of assignment statements).
79 </PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
80 All of these interfaces are macros. A "<STRONG>&</STRONG>" is not necessary before the
81 variables <EM>y</EM> and <EM>x</EM>.

85 The <STRONG>getyx</STRONG>, <STRONG>getparyx</STRONG>, <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> macros are described in the
86 XSI Curses standard, Issue 4.
88 This implementation also provides functions <STRONG>getbegx</STRONG>, <STRONG>getbegy</STRONG>, <STRONG>getcurx</STRONG>,
89 <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>getpary</STRONG> for compatibility with
90 older versions of curses.
92 Although X/Open Curses does not address this, many implementations pro-
93 vide members of the WINDOW structure containing values corresponding to
94 these macros. For best portability, do not rely on using the data in
95 WINDOW, since some implementations make WINDOW opaque (do not allow
96 direct use of its members).
98 Besides the problem of opaque structures, the data stored in like-named
99 members may not have like-values in different implementations. For
100 example, the WINDOW._maxx and WINDOW._maxy values in ncurses have (at
101 least since release 1.8.1) differed by one from some other implementa-
102 tions. The difference is hidden by means of the macro <STRONG>getmaxyx</STRONG>.
