#include <db_cxx.h>
int
DbEnv::log_register(Db *dbp, const char *name);
Description
The DbEnv::log_register method registers a filename with the specified Berkeley DB
environment's log manager. The log manager records all filename 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 filename 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.
Errors
The DbEnv::log_register method may fail and throw an exception or return a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
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.
