### hb_ot_shape_glyphs_closure ()

    void
    hb_ot_shape_glyphs_closure (hb_font_t *font,
                                hb_buffer_t *buffer,
                                const hb_feature_t *features,
                                unsigned int num_features,
                                hb_set_t *glyphs);

Computes the transitive closure of glyphs needed for a specified input buffer under the given font and feature list. The closure is computed as a set, not as a list.

#### Parameters

font | hb_font_t to work upon |
buffer | The input buffer to compute from |
features | The features enabled on the buffer. | [array length=num_features]
num_features | The number of features enabled on the buffer |
glyphs | The hb_set_t set of glyphs comprising the transitive closure of the query. | [out]
