DESCRIPTION

14       The function post_form displays a form to its associated subwindow.  To
15       trigger physical display of the subwindow, use refresh or some  equiva‐
16       lent curses routine (the implicit doupdate triggered by an curses input
17       request will do).
18
19       The function unpost_form erases form from its associated subwindow.
