menus(S)


menus -- character based menus package

Syntax

cc ... -lmenu -lcurses

#include <menu.h>

Description

The menu(S) library is built using the curses(S) library, and any program using menus routines must call one of the curses routines must initialization routines, such as initscr(S).

The menus package gives the applications programmer a terminal-independent method of creating and customizing menus for user interaction. The menus package includes: item routines, which are used to create and customize menu items; and menu routines, which are used to create and customize menus, assign pre- and post-processing routines and display and interact with menus.

Current default values for item attributes

The menus package establishes initial current default values for item attributes. During item initialization, each item attribute is assigned the current default value for that attribute.

An application can change or retrieve a current default attribute value by calling a set or retrieve routine with a NULL item pointer. If an application changes a current default item attribute value, subsequent items created using new_item(S) have the new default attribute value. (The attributes of previously created items are not changed if a current default attribute value is changed.)

An incorrect argument was passed to the routine

E_POSTED
The menu is already posted

E_CONNECTED
