    #include <db_cxx.h>

    int
    DbEnv::log_unregister(int32_t DB *dbp);

# Description

The DbEnv::log_unregister method function unregisters the file represented by the dbp parameter from the Berkeley DB environment's log manager.

The DbEnv::log_unregister 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_unregister 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_unregister 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_unregister 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.
