</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
<STRONG>wresize</STRONG>, an <EM>ncurses</EM> extension to the <EM>curses</EM> library, reallocates
storage for <EM>win</EM>, adjusting its dimensions to <EM>lines</EM> and <EM>columns</EM>. If
either dimension is larger than its current value, <EM>ncurses</EM> fills the
expanded part of the window with the window's background character as
configured by <STRONG><A HREF="curs_bkgd.3x.html">wbkgdset(3x)</A></STRONG> (wide-character API: <STRONG><A HREF="curs_bkgrnd.3x.html">wbkgrndset(3x)</A></STRONG>).
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
<STRONG>wresize</STRONG> returns <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure. It fails if either
<EM>lines</EM> or <EM>columns</EM> is less than or equal to zero, or if an error occurs
while (re)allocating memory for <EM>win</EM>.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
The only restriction placed on the values of <EM>lines</EM> and <EM>columns</EM> is that
they be greater than zero. They are <EM>not</EM> compared to the dimensions of
the <EM>curses</EM> screen; this keeps the logic of <STRONG><A HREF="resizeterm.3x.html">resizeterm(3x)</A></STRONG> simple. The
caller must ensure that <EM>win</EM>'s dimensions fit within those of the
screen.
</PRE><H2><a name="h2-EXTENSIONS">EXTENSIONS</a></H2><PRE>
<STRONG>wresize</STRONG> is an <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> extension, and is not found in SVr4 <EM>curses</EM>,
4.4BSD <EM>curses</EM>, or any other previous <EM>curses</EM> implementation.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
Applications employing <EM>ncurses</EM> extensions should condition their use on
the visibility of the <STRONG>NCURSES_VERSION</STRONG> preprocessor macro.
NetBSD <EM>curses</EM> adopted <EM>wresize</EM> in 2001 (release 1.5.3), and <EM>PDCurses</EM> in
2004 (version 2.7).
It is not possible to resize windows with SVr4 <EM>curses</EM>.
</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
Thomas Dickey developed <EM>wresize</EM> as an extension to BSD <EM>curses</EM> in 1988,
and brought it to <EM>ncurses</EM> in mid-1995.
