<b>Description: DbTxn::abort</b>
<p>The DbTxn::abort method causes an abnormal termination of the transaction.
The log is played backward, and any necessary undo operations are done
through the <b>tx_recover</b> function specified to
<a href="../api_cxx/env_set_app_dispatch.html">DbEnv::set_app_dispatch</a>. Before DbTxn::abort returns, any
locks held by the transaction will have been released.</p>
<p>In the case of nested transactions, aborting a parent transaction causes
all children (unresolved or not) of the parent transaction to be aborted.</p>
<p>All cursors opened within the transaction must be closed before the
transaction is aborted.</p>
<p>After DbTxn::abort has been called, regardless of its return, the
<a href="../api_cxx/txn_class.html">DbTxn</a> handle may not be accessed again.</p>
<p>The DbTxn::abort 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.
