| 31 | .SH NAME | 
|---|
| 32 | \fBmitem_value\fR - set and get menu item values | 
|---|
| 33 | .SH SYNOPSIS | 
|---|
| 34 | \fB#include <menu.h>\fR | 
|---|
| 35 | .br | 
|---|
| 36 | int set_item_value(ITEM *item, bool value); |

|---|

| 40 | .SH DESCRIPTION | 
|---|
| 41 | If you turn off the menu option \fBO_ONEVALUE\fR (e.g., with | 
|---|
| 42 | \fBset_menu_opts\fR or \fBmenu_opts_off\fR; see \fBmenu_opts\fR(3X)), the menu | 
|---|
| 43 | becomes multi-valued; that is, more than one item may simultaneously be | 
|---|
| 44 | selected. | 
|---|
| 45 |  | 
|---|
| 46 | In a multi_valued menu, you can used \fBset_item_value\fR to select the | 
|---|
| 47 | given menu item (second argument \fBTRUE\fR) or deselect it (second argument | 
|---|
| 48 | \fBFALSE\fR). | 
|---|
| 49 | .SH RETURN VALUE | 
|---|
| 50 | The function \fBset_item_value\fR returns one of the following: | 
|---|
| 51 | .TP 5 |

|---|
| 54 | .TP 5 | 
|---|
| 55 | \fBE_SYSTEM_ERROR\fR | 
|---|
| 56 | System error occurred (see \fBerrno\fR). | 
|---|
| 57 | .TP 5 | 
|---|
| 58 | \fBE_REQUEST_DENIED\fR | 
|---|
| 59 | The menu driver could not process the request. |
