  39  * bt_ctf_field_type_get and bt_ctf_field_type_put: increment and decrement
  40  * the field type's reference count.
  41  *
  42  * You may also use bt_ctf_object_get_ref() and bt_ctf_object_put_ref() with field type objects.
  43  *
  44  * These functions ensure that the field type won't be destroyed while it
  45  * is in use. The same number of get and put (plus one extra put to
  46  * release the initial reference done at creation) have to be done to
  47  * destroy a field type.
  48  *
  49  * When the field type's reference count is decremented to 0 by a
  50  * bt_ctf_field_type_put, the field type is freed.
  51  *
  52  * @param type Field type.
