NAME¶
set_menu_mark, menu_mark - get and set the menu mark stringSYNOPSIS¶
#include <menu.h>int set_menu_mark(MENU *menu, const char *mark);
const char *menu_mark(const MENU *menu);
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).
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).
