Library calls <STRONG><A HREF="curs_window.3x.html">curs_window(3x)</A></STRONG>
A new full-screen window is created by calling <STRONG>newwin(0,0,0,0)</STRONG>.
+ Regardless of the function used for creating a new window (e.g.,
+ <STRONG>newwin</STRONG>, <STRONG>subwin</STRONG>, <STRONG>derwin</STRONG>, <STRONG>newpad</STRONG>), rather than a duplicate (with <STRONG>dupwin</STRONG>),
+ all of the window modes are initialized to the default values. These
+ functions set window modes after a window is created:
+
+ idcok, idlok, immedok, keypad, leaveok, nodelay, scrollok,
+ setscrreg, syncok, wbkgdset, wbkgrndset, and wtimeout

Calling <STRONG>delwin</STRONG> deletes the named window, freeing all memory associated
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
The XSI Curses standard, Issue 4 describes these functions.
+ X/Open Curses states regarding <STRONG>delwin</STRONG>:
+
+ <STRONG>o</STRONG> It must delete subwindows before deleting their parent.
+
+ <STRONG>o</STRONG> If <STRONG>delwin</STRONG> is asked to delete a parent window, it can only succeed
+ if the curses library keeps a list of the subwindows. SVr4 curses
+ kept a count of the number of subwindows rather than a list. It
+ simply returned <STRONG>ERR</STRONG> when asked to delete a subwindow. Solaris
+ X/Open curses does not even make that check, and will delete a par-
+ ent window which still has subwindows.
+
+ <STRONG>o</STRONG> Since release 4.0 (1996), ncurses maintains a list of windows for
+ each screen, to ensure that a window has no subwindows before al-
+ lowing deletion.
+
+ <STRONG>o</STRONG> NetBSD copied this feature of ncurses in 2003.
+ PDCurses follows the scheme used in Solaris X/Open curses.
