DB->get_type(DB *db, DBTYPE *type);
The DB->get_type method
stores the type of the underlying access method (and file format) into
the memory referenced by type.
The returned value is one of DB_BTREE, DB_HASH,
DB_RECNO, or DB_QUEUE. This value may be used to
determine the type of the database after a return from DB->open
with the type argument set to DB_UNKNOWN.
The DB->get_type interface may not be called before the DB->open
interface has been called.
The DB->get_type method may fail and return a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
Called before DB->open was called.
The DB->get_type method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB->get_type method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
