+ <STRONG>o</STRONG> which <STRONG>ungetch</STRONG>'s a <STRONG>KEY_RESIZE</STRONG> which will be read on the
+ next call to <STRONG>wgetch</STRONG>.
+
+ The <STRONG>KEY_RESIZE</STRONG> alerts an application that the screen
+ size has changed, and that it should repaint special
+ features such as pads that cannot be done automati-
+ cally.
+
+ Calling <STRONG>resizeterm</STRONG> or <STRONG>resize_term</STRONG> directly from a sig-
+ nal handler is unsafe. This indirect method is used
+ to provide a safe way to resize the ncurses data
+ structures.
+
+ If the environment variables <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> are set,
+ this overrides the library's use of the window size
+ obtained from the operating system. Thus, even if a SIG-
+ WINCH is received, no screen size change may be recorded.

+ It is possible to resize the screen with SVr4 curses, by
+
+ <STRONG>o</STRONG> exiting curses with <STRONG><A HREF="endwin.3x.html">endwin(3x)</A></STRONG> and
+
+ <STRONG>o</STRONG> resuming using <STRONG><A HREF="refresh.3x.html">refresh(3x)</A></STRONG>.
+
+ Doing that clears the screen and is visually distracting.
+
+ This extension of ncurses was introduced in mid-1995. It
+ was adopted in NetBSD curses (2001) and PDCurses (2003).
