NAME
menu - curses extension for programming menusSYNOPSIS
#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 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.Routine Name Index

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 usually give a link-error).
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.AUTHORS
