menu_post(3)        UNIX Programmer's Manual         menu_post(3)

NAME

     menu_post - write or erase menus from associated subwindows

SYNOPSIS

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

DESCRIPTION

     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.

RETURN VALUE

     These routines return one of the following:

     E_OK The routine succeeded.

     E_SYSTEM_ERROR
          System error occurred (see errno).

     E_BAD_ARGUMENT
          Routine detected an incorrect or out-of-range argument.

     E_POSTED
          The menu has already been posted.

     E_BAD_STATE
          Routine was called from an initialization or termina-
          tion function.

     E_NO_ROOM
          Menu is too large for its window. You should consider
          to use set_menu_format() to solve the problem.

     E_NOT_POSTED
          The menu has not been posted.

     E_NOT_CONNECTED
          No items are connected to the menu.
