menu(3X)                                                              menu(3X)



NAME
       menu - curses extension for programming menus

SYNOPSIS
       #include <menu.h>

DESCRIPTION
       The menu library provides terminal-independent facilities for composing
       menu systems on character-cell terminals.  The library  includes:  item
       routines,  which create and modify menu items; and menu routines, which
       group items into menus, display menus on the screen, and handle  inter-action interaction
       action with the user.

       The menu library uses the curses libraries, and a curses initialization
       routine such as initscr must be called before using any of these  func-tions. functions.
       tions.  To use the menu library, link with the options -lmenu -lcurses.


   Current Default Values for Item Attributes
       The menu library maintains a default value for  item  attributes.   You
       can  get  or  set  this default by calling the appropriate get_ or set_
       routine with a NULL item pointer.  Changing this default  with  a  set_
       function affects future item creations, but does not change the render-ing rendering
       ing of items already created.


   Routine Name Index
       The following table lists each menu routine and the name of the  manual
       page on which it is described.

RETURN VALUE
       Routines  that  return  pointers  return  NULL on error.  Routines that
       return an integer return one of the following error codes:

       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 is already posted.

       E_BAD_STATE
            Routine was called from an initialization or termination function.

       E_NO_ROOM
            Menu is too large for its window.

       E_NOT_POSTED
            The menu has not been posted.

       E_UNKNOWN_COMMAND
            The menu driver code saw an unknown request code.

       E_NO_MATCH
            Character failed to match.

       E_NOT_SELECTABLE
            The designated item cannot be selected.

       E_NOT_CONNECTED
            No items are connected to the menu.

       E_REQUEST_DENIED
            The menu driver could not process the request.

SEE ALSO
       curses(3X)  and  related  pages  whose names begin "menu_" for detailed
       descriptions of the entry points.

NOTES
       The header  file  <menu.h>  automatically  includes  the  header  files
       <curses.h> and <eti.h>.

       In your library list, libmenu.a should be before libncurses.a; that is,
       you want to say `-lmenu -lncurses', not the  other  way  around  (which
       would give you a link error using GNU ld(1) and many other linkers).

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