<p>
The object should not be closed while any other handle that refers
to it is not yet closed; for example, database environment handles
must not be closed while transactions in the environment have
not yet been committed or aborted. If there are open database
handles, they are all closed, and each of them will be synced on
close. The first error in the close operations, if any, is
returned at last, and the environment close procedures will
carry on anyway.
</p>
<p>
Where the environment was configured with
<a href="F_BerkeleyDB_DatabaseEnvironmentConfig_UseTxns.htm">UseTxns</a>, calling CloseForceSync
aborts any unresolved transactions. Applications should not depend
on this behavior for transactions involving Berkeley DB databases;
all such transactions should be explicitly resolved. The problem
with depending on this semantic is that aborting an unresolved
transaction involving database operations requires a database
handle. Because the database handles should have been closed before
calling CloseForceSync, it will not be possible to abort the
transaction, and recovery will have to be run on the Berkeley DB
environment before further operations are done.
</p>
<p>
In multithreaded applications, only a single thread may call
CloseForceSync.
