<h1>Description</h1>
<p>The Dbc.count method returns a count of the number of duplicate data
items for the key referenced by the
cursor.
If the underlying database does not support duplicate data items the call
will still succeed and a count of 1 will be returned.
<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
<p>If the <b>cursor</b> argument is not yet initialized, the Dbc.count method throws an exception that encapsulates EINVAL.
<p>Otherwise, the Dbc.count method throws an exception that encapsulates a non-zero error value on
failure.
<h1>Errors</h1>
<p>The Dbc.count 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 Dbc.count method may fail and throw
a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
will fail in the same way.
<h3>Class</h3>
