menus - curses extension for programming menus
#include <menu.h>
The menus 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 menus 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 menus library, link with the options -lmenu -lcurses.
The menus 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.
The following table lists each menu routine and the name of the manual page on which it is described.

Routines that return pointers return NULL on error. Routines that return an integer return one of the following error codes:
curses(3) and 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 libncurses.a; that is, you want to say -lmenu -ncurses, not the other way around (which would give you a link error using many linkers).
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
