# DbLog.db_unregister

`

###

    import com.sleepycat.db.*;

    public void db_unregister(int fid)
    	throws DbException;

# Description

The DbLog.db_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 DbLog.db_unregister method throws an exception that encapsulates an errno on failure.

# Errors

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

The DbLog.db_unregister method may fail and throw an exception for any of the errors specified for the following Berkeley DB and C library functions: abort(3), close(3), dbenv->db_paniccall(3), fcntl(3), fflush(3), fprintf(3), free(3), fsync(3), getenv(3), getpid(3), getuid(3), isdigit(3), lseek(3), malloc(3), memcpy(3), memset(3), open(3), sigfillset(3), sigprocmask(3), snprintf(3), stat(3), strerror(3), strlen(3), time(3), unlink(3), vfprintf(3), vsnprintf(3), and write(3).

In addition, the DbLog.db_unregister method may fail and throw an exception encapsulating errno for the following conditions:

EINVAL
  An invalid flag value or parameter was specified.
