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 charactercell
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 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 cre-ated. created.

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_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_BAD_STATE
Routine was called from an initialization or termination function.
E_NO_MATCH
Character failed to match.
E_NO_ROOM
Menu is too large for its window.
E_NOT_CONNECTED
No items are connected to the menu.
E_NOT_POSTED
The menu has not been posted.
E_NOT_SELECTABLE
The designated item cannot be selected.
E_POSTED
The menu is already posted.
E_REQUEST_DENIED
The menu driver could not process the request.
E_SYSTEM_ERROR
System error occurred (see errno).
E_UNKNOWN_COMMAND
The menu driver code saw an unknown request code.
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 usually give a link-error).
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD ver-sions. versions.
