The XSI Curses standard, Issue 4 describes these functions.
+ X/Open Curses states regarding delwin:
+
+ o It must delete subwindows before deleting their parent.
+
+ o If delwin 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 ERR 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.
+
+ o 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.
+
+ o NetBSD copied this feature of ncurses in 2003.
+ PDCurses follows the scheme used in Solaris X/Open curses.
