<b>Description: DB_TXN->abort</b>
|
|
<p>The DB_TXN->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_c/env_set_app_dispatch.html">DB_ENV->set_app_dispatch</a>. Before DB_TXN->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 DB_TXN->abort has been called, regardless of its return, the
|
|
<a href="../api_c/txn_class.html">DB_TXN</a> handle may not be accessed again.</p>
|
|
<p>The DB_TXN->abort method
|
|
returns a non-zero error value on failure
|
|
and 0 on success.
