Instead there is only the -DB_ENV structure. This means that DB_ENV references should -be passed around by your application instead of passing around DB_LOCKTAB -or DB_TXNMGR references. -<p>Each of the following functions: -<p><blockquote><pre>lock_detect -lock_get -lock_id -lock_put -lock_stat -lock_vec</pre></blockquote> -<p>should have its first argument, a reference to the DB_LOCKTAB structure, -replaced with a reference to the enclosing DB_ENV structure. For -example, the following line of code from a Berkeley DB 2.X application: -<p><blockquote><pre>DB_LOCKTAB *lt; -DB_LOCK lock; - ret = lock_put(lt, lock);</pre></blockquote> -<p>should now be written as follows: -<p><blockquote><pre>DB_ENV *dbenv; -DB_LOCK *lock; - ret = lock_put(dbenv, lock);</pre></blockquote> -<p>Similarly, all of the functions: -<p><blockquote><pre>log_archive -log_compare -log_file -log_flush -log_get -log_put -log_register -log_stat -log_unregister</pre></blockquote> -<p>should have their DB_LOG argument replaced with a reference to a -DB_ENV structure, and the functions: -<p><blockquote><pre>memp_fopen -memp_register -memp_stat -memp_sync -memp_trickle</pre></blockquote> -<p>should have their DB_MPOOL argument replaced with a reference to a -DB_ENV structure. -<p>You should remove all references to DB_LOCKTAB, DB_LOG, DB_MPOOL, and -DB_TXNMGR structures from your application, they are no longer useful -in any way. In fact, a simple way to identify all of the places that -need to be upgraded is to remove all such structures and variables -they declare, and then compile.
