SYNOPSIS    [Toc]    [Back]

       #include <menu.h>
       int post_menu(MENU *menu);
       int unpost_menu(MENU *menu);

DESCRIPTION    [Toc]    [Back]

       The function post_menu displays a menu to  its  associated
       subwindow.   To trigger physical display of the subwindow,
       use  refresh  or  some  equivalent  curses  routine   (the
       implicit  doupdate  triggered  by  an curses input request
       will do). post_menu resets the  selection  status  of  all
       items.

       The  function  unpost_menu erases menu from its associated
       subwindow.
