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>RETURN VALUE</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>NOTES</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>.</PRE><H2>PORTABILITY</H2><PRE> The <STRONG>getyx</STRONG>, <STRONG>getparyx</STRONG>, <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> functions 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.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> <STRONG><A HREF="curs_getyx.3x.html">curs_getyx(3x)</A></STRONG></PRE><HR><ADDRESS>Man(1) output converted with<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a></ADDRESS></BODY></HTML>⌨️ 快捷键说明
