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)).
