.SH SYNOPSIS
\fB#include <menu.h>\fR
.br
int set_menu_items(MENU *menu, ITEM **items);
.br
ITEM **menu_items(const MENU *menu);
.br
int item_count(const MENU *menu);
.br
.SH DESCRIPTION
The function \fBset_menu_items\fR changes the item pointer array of the given
\fImenu\fR.  The array must be terminated by a \fBNULL\fR.
.PP
The function \fBmenu_items\fR returns the item array of the given menu.
.PP
The function \fBitem_count\fR returns the count of items in \fImenu\fR.
.SH RETURN VALUES
The function \fBmenu_items\fR returns a pointer (which may be \fBNULL\fR).
It does not set errno.
.PP
The function \fBitem_count\fR returns \fBERR\fR (the general \fBcurses\fR error
return value) if its \fImenu\fP parameter is \fBNULL\fP.
.PP
The function \fBset_menu_items\fR returns one of the following codes on error:
.TP 5
.B E_OK
The routine succeeded.
.TP 5
.B E_BAD_ARGUMENT

.SH NOTES
The header file \fB<menu.h>\fR automatically includes the header file
\fB<curses.h>\fR.
.SH PORTABILITY
These routines emulate the System V menu library.  They were not supported on
Version 7 or BSD versions.

The SVr4 menu library documentation specifies the \fBitem_count\fR error value
as -1 (which is the value of \fBERR\fR).
