<h1>Description</h1>
<p>The Dbc::close method discards the cursor.
<p>It is possible for the Dbc::close method to return
<a href="../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>, signaling that any enclosing transaction should
be aborted.  If the application is already intending to abort the
transaction, this error should be ignored, and the application should
proceed.
<p>After Dbc::close has been called, regardless of its return, the
cursor handle may not be used again.
<p>The Dbc::close method either returns a non-zero error value or throws an exception that
encapsulates a non-zero error value on failure, and returns 0 on success.
<h1>Errors</h1>
<p>The Dbc::close method may fail and throw an exception or return a non-zero error for the following conditions:
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>The cursor was previously closed.
</dl>
<p>If the operation was selected to resolve a deadlock, the
Dbc::close method will fail and
and either return <a href="../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a> or
throw a <a href="../api_cxx/deadlock_class.html">DbDeadlockException</a> exception.
<p>The Dbc::close method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the Dbc::close method may fail and
either return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw a
<a href="../api_cxx/runrec_class.html">DbRunRecoveryException</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
