.SH NAME
menus \- character based menus package
.SH SYNOPSIS
.nf
\fB#include <menu.h>\fR
.fi
.SH DESCRIPTION
The \fBmenu\fR library is built using the \fBcurses\fR library, and any program
using menus routines must call one of the \fBcurses\fR initialization routines,
such as \fBinitscr\fR. A program using these routines must be compiled with
\fB-lmenu\fR and \fB-lcurses\fR on the \fBcc\fR command line.
.sp
.LP
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.
.SS "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 the appropriate set or retrieve
routine with a \fINULL\fR item pointer. If an application changes a current
default item attribute value, subsequent items created using \fBnew_item()\fR
will have the new default attribute value. The attributes of previously created
items are not changed if a current default attribute value is changed.
.SS "Routine Name Index"
The following table lists each menus routine and the name of the manual page on
which it is described.
