- ntdb functions return NTDB_SUCCESS (ie 0) on success, and a negative
error on failure, whereas tdb functions returned 0 on success, and
-1 on failure. tdb then used tdb_error() to determine the error;
- this is also supported in ntdb to ease backwards compatibility,
- though the other form is preferred.
+ this API is nasty if we ever want to support threads, so is not supported.
- ntdb's ntdb_fetch() returns an error, tdb's returned the data directly
(or tdb_null, and you were supposed to check tdb_error() to find out why).
