DESCRIPTION

15       The function post_form displays a form to its associated subwindow.  To
16       trigger  physical  display  of  the  subwindow, use refresh(3X) or some
17       equivalent curses routine (the implicit doupdate triggered by an curses
18       input request will do).

20       The function unpost_form erases form from its associated subwindow.
