Functions

hb_ot_name_list_names ()

const hb_ot_name_entry_t *
hb_ot_name_list_names (hb_face_t *face,
                       unsigned int *num_entries);

Enumerates all available name IDs and language combinations. Returned array is owned by the face and should not be modified. It can be used as long as face is alive.

Parameters

face

font face.

 

num_entries

number of returned entries.

[out][allow-none]

Returns

Array of available name entries.

[out][transfer none][array length=num_entries]

hb_ot_name_get_utf16 ()

unsigned int
hb_ot_name_get_utf16 (hb_face_t *face,
