SYNOPSIS DESCRIPTION RETURN VALUE SEE ALSO NOTES PORTABILITY AUTHORS

#include <menu.h>
int set_menu_opts(MENU *menu, Menu_Options opts);
int menu_opts_on(MENU *menu, Menu_Options opts);
int menu_opts_off(MENU *menu, Menu_Options opts);
Menu_Options menu_opts(const MENU *menu);

The function set_menu_opts sets all the given menu's option bits (menu option bits may be logically-OR'ed together).

The function menu_opts_on turns on the given option bits, and leaves others alone.

The function menu_opts_off turns off the given option bits, and leaves others alone.

The function menu_opts returns the menu's current option bits.

The following options are defined (all are on by default):

O_ONEVALUE
	Only one item can be selected for this menu.
O_SHOWDESC
	Display the item descriptions when the menu is posted.
O_ROWMAJOR
	Display the menu in row-major order.
O_IGNORECASE
	Ignore the case when pattern-matching.
O_SHOWMATCH
	Move the cursor to within the item name while pattern-matching.
O_NONCYCLIC
	Don't wrap around next-item and previous-item, requests to the other end of the menu.
O_MOUSE_MENU
	If user clicks with the mouse and it does not fall on the currently active menu, push KEY_MOUSE and the MEVENT data back on the queue to allow processing in another part of the calling program.

Except for menu_opts, each routine returns one of the following:

E_OK	The routine succeeded.
E_SYSTEM_ERROR
	System error occurred (see errno(3)).
E_POSTED
	The menu is already posted.

The header file <menu.h> automatically includes the header file <curses.h>.

These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
