###

    import com.sleepycat.db.*;

    public void log_unregister(int fid)
    	throws DbException;

# Description

The DbEnv.log_unregister method disassociates the file name to file identification number mapping for the file identification number specified by the fid parameter. The file identification number may then be reused.

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

# Errors

If a fatal error occurs in Berkeley DB, the DbEnv.log_unregister method will fail and throw a DbRunRecoveryException, at which point all subsequent database calls will fail in the same way.

In addition, 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.

In addition, the DbEnv.log_unregister method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
