.SH DESCRIPTION
.sp
.LP
Unlike single-valued menus, multi-valued menus enable the end-user to select
one or more items from a menu. \fBset_item_value()\fR sets the selected value
of the \fIitem\fR \(em \fBTRUE\fR (selected) or \fBFALSE\fR (not selected).
\fBset_item_value()\fR may be used only with multi-valued menus. To make a menu
multi-valued, use \fBset_menu_opts\fR or \fBmenu_opts_off()\fR to turn off the
option \fBO_ONEVALUE\fR. (See \fBmenu_opts\fR(3CURSES)).

\fBitem_value()\fR returns the select value of \fIitem\fR, either \fBTRUE\fR
