Db.fd

import com.sleepycat.db.*;
public int fd()
throws DbException;
Description
The Db.fd method
returns a file descriptor representative of the underlying database.
This method does not fit well into the Java framework and may be removed
in subsequent releases.
The Db.fd
method throws an exception that encapsulates a non-zero error value on
failure.
Errors
If a fatal error occurs in Berkeley DB, the Db.fd method will fail and throw a
DbRunRecoveryException, at which point all subsequent database
calls will fail in the same way.
In addition, the Db.fd method may fail and
throw an exception
for errors specified for other Berkeley DB and C library or system methods.
