int
DB_TXN->set_name(DB_TXN *txn, const char *name);  

The DB_TXN->set_name() method associates the specified string with the transaction. The string is returned by DB_ENV->txn_stat() and displayed by DB_ENV->txn_stat_print().

If the database environment has been configured for logging and the Berkeley DB library was configured with --enable-diagnostic, a debugging log record is written including the transaction ID and the name.

The DB_TXN->set_name() method may be called at any time during the life of the application.

The DB_TXN->set_name() method returns a non-zero error value on failure and 0 on success.
