  38  *
  39  * @param type_id
  40  * A unsinged int type specified by the KCDATA.
  41  *
  42  * @param buffer
  43  * pointer to data area where type definition will be saved.

  48  * @return struct kcdata_type_definition *
  49  * pointer to a malloc'ed buffer holding the type definition and each subtype defintion for its fields.
  50  * It may return NULL if no type with id == type_id is found.
  51  * Note: The caller is responsible to free() the memory when its no longer used.
  52  *
  53  * @discussion
  54  * This function queries the known type definitions table. If found the defintion data is returned
  55  * else NULL is returned. It is advised to cache the return value from this function since the data
  56  * is always going to be the same for same type_id. The definition setup requires memory on heap.
  57  * The caller should make sure to free() the data once its done with using it.
