menu(3)                                                   menu(3)

       menu - curses extension for programming menus

       #include <menu.h>

       The  menu library provides terminal-independent facilities
       for composing menu systems  on  character-cell  terminals.
       The library includes: item routines, which create and mod-
       ify menu items; and menu routines, which group items  into
       menus, display menus on the screen, and handle interaction
       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  functions.   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
       rendering of items already created.

       Routines  that return pointers return NULL on error.  Rou-
       tines that return an integer return one of  the  following
       error codes:

       E_OK The routine succeeded.


menu(3)                                                   menu(3)

            System error occurred (see errno).

            Routine  detected  an incorrect or out-of-range argu-

            The menu is already posted.

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

            Menu is too large for its window.

            The menu has not been posted.

            The menu driver code saw an unknown request code.

            Character failed to match.

            The designated item cannot be selected.

            No items are connected to the menu.

            The menu driver could not process the request.

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

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

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

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