#include <db_cxx.h> int 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 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.
