14
15 bool waffle_attrib_list_get(const int32_t attrib_list[], int32_t key,
16 int32_t *value);
17
18 bool waffle_attrib_list_get_with_default(const int32_t attrib_list[],
19 int32_t key, int32_t *value,
20 int32_t default_value);

23 int32_t *value);

26 An attribute list is a zero-terminated list of int32_t key/value pairs
27 or a null pointer. A null pointer is interpreted as an empty list,
28 whose only member is the terminal zero. For concrete examples of
29 attribute lists, see the "Examples" section in waffle_config(3).
30
31 All attribute list functions can be called before waffle has been
32 successfully initialized with waffle_init(3).
33
34 waffle_attrib_list_length()
35 Return the number of key/value pairs in the list.
36
37 waffle_attrib_list_get()
38 Get the value associated with key. If the list does not contain the
39 key, then value is not dereferenced. Return true if and only if the
40 list contains the key.
41
42 waffle_attrib_list_get_with_default()
43 Equivalent to waffle_attrib_list_get() except that if the list does
44 not contain the key then value is set to a default_value.
45
46 waffle_attrib_list_update()
47 Update the value associated with key. If the list does not contain
48 the key then the list is not modified. Return true if and only if
49 the list contains the key.
50
52 All attribute list functions set the error code to WAFFLE_NO_ERROR and
53 can be called before waffle has been successfully initialized with
54 waffle_init(3).
55
56 See waffle_error(3) for the complete list of waffle's error codes.
