OpenDarwin 7.2.1 - man page for menu_mark (opendarwin section 3x)

menu_mark(3X)												menu_mark(3X)

NAME
menu_mark - get and set the menu mark string
SYNOPSIS
#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 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 NULL on error. The function set_menu_mark may return the following error codes: E_OK The routine succeeded. E_SYSTEM_ERROR System error occurred (see errno). E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.
SEE ALSO
curses(3X), menu(3X).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
