#include <db_cxx.h>int Db::set_lorder(int lorder);
Set the byte order for integers in the stored database metadata. The number should represent the order as an integer; for example, big endian order is the value 4,321, and little endian order is the value 1,234. If lorder is not explicitly set, the host order of the machine where the Berkeley DB library was compiled is used.
The value of lorder is ignored except when databases are being created. If a database already exists, the byte order it uses is determined when the database is opened.
The access methods provide no guarantees about the byte ordering of the application data stored in the database, and applications are responsible for maintaining any necessary ordering.
The Db::set_lorder interface may be used only to configure Berkeley DB before the Db::open interface is called.
The Db::set_lorder 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::set_lorder method may fail and throw an exception or return a non-zero error for the following conditions:
Called after Db::open was called.
The Db::set_lorder method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the Db::set_lorder method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
