    public void log_unregister(Db dbp)
    	throws DbException;

# 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 throws an exception that encapsulates a non-zero error value on failure.

# Errors

The DbEnv.log_unregister method may fail and throw an exception encapsulating 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 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 throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
