## Functions

### hb_aat_layout_feature_type_get_name_id ()

    hb_ot_name_id_t
    hb_aat_layout_feature_type_get_name_id
                                   (hb_face_t *face,
                                    hb_aat_layout_feature_type_t feature_type);

Fetches the name identifier of the specified feature type in the face's `name` table.

#### Parameters

face | hb_face_t to work upon |
feature_type | The hb_aat_layout_feature_type_t of the requested feature type |

#### Returns

Name identifier of the requested feature type

Since: 2.2.0

### hb_aat_layout_feature_type_get_selector_infos ()

    unsigned int
    hb_aat_layout_feature_type_get_selector_infos
                                   (hb_face_t *face,
                                    hb_aat_layout_feature_type_t feature_type,
                                    unsigned int start_offset,
                                    unsigned int *selector_count,
                                    hb_aat_layout_feature_selector_info_t *selectors,
                                    unsigned int *default_index);

Fetches a list of the selectors available for the specified feature in the given face.

If upon return, `default_index` is set to HB_AAT_LAYOUT_NO_SELECTOR_INDEX, then the feature type is non-exclusive. Otherwise, `default_index` is the index of the selector that is selected by default.

#### Parameters

face | hb_face_t to work upon |
feature_type | The hb_aat_layout_feature_type_t of the requested feature type |
start_offset | offset of the first feature type to retrieve |
selector_count | Input = the maximum number of selectors to return; Output = the actual number of selectors returned (may be zero). | [inout][optional]
selectors | A buffer pointer. The selectors available for the feature type queries. | [out caller-allocates][array length=selector_count][optional]
default_index | The index of the feature's default selector, if any. | [out][optional]

#### Returns

Number of all available feature selectors

Since: 2.2.0

### hb_aat_layout_get_feature_types ()

                                     unsigned int *feature_count,
                                     hb_aat_layout_feature_type_t *features);

Fetches a list of the AAT feature types included in the specified face.

#### Parameters

face | hb_face_t to work upon |
start_offset | offset of the first feature type to retrieve |
feature_count | Input = the maximum number of feature types to return; Output = the actual number of feature types returned (may be zero). | [inout][optional]

#### Returns

Number of all available feature types.

Since: 2.2.0
