DESCRIPTION

15       The function post_menu displays a menu 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).  post_menu resets the selection status of all
19       items.
20
21       The function unpost_menu erases menu from its associated subwindow.
