DbEnv::log_register |
#include <db_cxx.h>int DbEnv::log_register(Db *dbp, const char *name);
The DbEnv::log_register method registers a file name with the specified Berkeley DB environment's log manager. The log manager records all file name mappings at each checkpoint so that a recovery process can identify the file to which a record in the log refers.
The dbp argument should be a reference to the Db object being registered. The name argument should be a file name appropriate for opening the file in the environment, during recovery.
The DbEnv::log_register 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 DbEnv::log_register method may fail and throw an exception or return a non-zero error for the following conditions:
The DbEnv::log_register 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 DbEnv::log_register 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.
