40 | * These functions ensure that the field won't be destroyed when it | |
41 | * is in use. The same number of get and put (plus one extra put to | |
42 | * release the initial reference done at creation) have to be done to | |
43 | * destroy a field. | |

45 | * When the field's reference count is decremented to 0 by a bt_ctf_field_put, | |
46 | * the field is freed. | |
