53 *
54 * @discussion
55 * This function queries the known type definitions table. If found the defintion data is returned
56 * else NULL is returned. It is advised to cache the return value from this function since the data
57 * is always going to be the same for same type_id. The definition setup requires memory on heap.
58 * The caller should make sure to free() the data once its done with using it.
