menus - menu library
Curses Menu Library (libmenu, -lmenu)
#include <menu.h>
The menus library provides a terminal independent menu system using the
curses(3) library. Before using the menus functions the terminal must be
set up by curses(3) using the initscr() function or similar. Programs
using menus functions must be linked with the curses(3) library.
The menus library provides facilities for defining menu items, placing a
menu on the terminal screen, assign pre- and post-change operations and
setting the attributes of both the menu and its items.
Defining default attributes for menus and items [Toc] [Back]
The menus library allows any settable attribute or option of both the
menu and item objects to be defined such that any new menu or item automatically
inherits the value as default. Setting the default value will
not affect any item or menu that has already been created but will be
applied to subsequent objects. To set the default attribute or option
the set routine is passed a NULL pointer in the item or menu parameter
when calling the set routine. The current default value can be retrieved
by calling the get routine with a NULL pointer for the item or menu
parameter.
