.SH NAME
\fBmitem_opts\fR - set and get menu item options
.SH SYNOPSIS
\fB#include <menu.h>\fR
.br
int set_item_opts(ITEM *item, OPTIONS opts);
.br
int item_opts_on(ITEM *item, OPTIONS opts);
.br
int item_opts_off(ITEM *item, OPTIONS opts);
.br
OPTIONS item_opts(const ITEM *item);
.br
.SH DESCRIPTION
The function \fBset_item_opts\fR sets all the given item's option bits (menu
option bits may be logically-OR'ed together).

The function \fBitem_opts_on\fR turns on the given option bits, and leaves
others alone.

The function \fBitem_opts_off\fR turns off the given option bits, and leaves
others alone.

The function \fBitem_opts\fR returns the item's current option bits.

There is only one defined option bit mask, \fBO_SELECTABLE\fR.  When this is
on, the item may be selected during menu processing.  This option defaults
to on.
.SH RETURN VALUE
Except for \fBitem_opts\fR, each routine returns one of the following:
.TP 5
\fBE_OK\fR
The routine succeeded.
.TP 5
\fBE_SYSTEM_ERROR\fR
System error occurred (see \fBerrno\fR).
.SH SEE ALSO
\fBcurses\fR(3X), \fBmenu\fR(3X).
.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.
