### Description: DB->get_type

The DB->get_type method returns the type of the underlying access method (and file format). The type 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 parameter set to DB_UNKNOWN.

The DB->get_type method returns a non-zero error value on failure and 0 on success.

### Parameters

### Errors

EINVAL
  If the method was called before DB->open was called; or if an invalid flag value or parameter was specified.
