Имя (Name)

set_menu_mark, menu_mark - get and set the menu mark string


Синопсис (Synopsis)

#include <menu.h>

int set_menu_mark(MENU *menu, const char *mark); const char *menu_mark(const MENU *menu);


Описание (Description)

In order to make menu selections visible on older terminals without highlighting or color capability, the menu library marks selected items in a menu with a prefix string.

The function set_menu_mark sets the mark string for the given menu. Calling set_menu_mark with a null menu item will abolish the mark string. Note that changing the length of the mark string for a menu while the menu is posted is likely to produce unhelpful behavior.

The default string is "-" (a dash). Calling set_menu_mark with a non-NULL menu argument will change this default.

The function menu_mark returns the menu's mark string (or NULL if there is none).


Возвращаемое значение (Return value)

The function menu_mark returns a pointer (which may be NULL). It does not set errno.

The function set_menu_mark may return the following error codes:

E_OK The routine succeeded.

E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.

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