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.)
