    import com.sleepycat.db.*;

    public void lock_id_free(int id)
        throws DbException;

# Description

The DbEnv.lock_id_free method frees a locker ID allocated by the DbEnv.lock_id method.

The DbEnv.lock_id_free method throws an exception that encapsulates a non-zero error value on failure.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  The locker ID is invalid or locks are still held by this locker ID.

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