given a unique integral ID for a plugin:

        lrdf_uris* set_uris = lrdf_get_setting_uris(id);

        if (set_uris) {
                for (uint32_t i = 0; i < (uint32_t) set_uris->count; ++i) {
                        if (char* label = lrdf_get_label(set_uris->items[i])) {
                                labels.push_back(label);
                                presets[label] = set_uris->items[i];
                        }
                }
                lrdf_free_uris(set_uris);
        }

        // GTK2FIX find an equivalent way to do this with a vector (needed by
GUI apis)
        // labels.unique();

        return labels;
