<dd><p>This method frees up all the per-process resources associated with
the specified transaction, neither committing nor aborting the
transaction. The transaction will be keep in “unresolved” state. This
call may be used only after calls to “dbenv.txn_recover()”. A
“unresolved” transaction will be returned again thru new calls to
“dbenv.txn_recover()”.</p>
<p>For example, when there are multiple global transaction managers
recovering transactions in a single Berkeley DB environment, any
transactions returned by “dbenv.txn_recover()” that are not handled
by the current global transaction manager should be discarded using
“txn.discard()”.</p>
