    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 termination 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.
     

    SEE ALSO

    curses(3X), menu(3X).  

    NOTES

    The header file <menu.h> automatically includes the header file <curses.h>.  

    PORTABILITY

    These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
