set_menu_opts, menu_opts_on, menu_opts_off, menu_opts - set and get menu options #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):

5 O_ONEVALUE Only one item can be selected for this menu.

5 O_SHOWDESC Display the item descriptions when the menu is posted.

5 O_ROWMAJOR Display the menu in row-major order.

5 O_IGNORECASE Ignore the case when pattern-matching.

5 O_SHOWMATCH Move the cursor to within the item name while pattern-matching.

5 O_NONCYCLIC Don't wrap around next-item and previous-item, requests to the other end of the menu.

5 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:

5 E_OK The routine succeeded.

5 E_SYSTEM_ERROR System error occurred (see errno(3)).

5 E_POSTED The menu is already posted.
