#include <db_cxx.h>
Db::get_type(DBTYPE *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 may not be called before the Db::open() method is called.

The Db::get_type() method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.



The type parameter references memory into which the type of the underlying access method is copied.


The Db::get_type() method may fail and throw a DbException exception, encapsulating one of the following non-zero errors, or return one of the following non-zero errors:


If the method was called before Db::open() was called; or if an invalid flag value or parameter was specified.
