<p>Applications calling any of these functions should update their calls
|
|||
|
|
to use the enclosing <a href="../api_reference/C/env.html" class="olink">DB_ENV</a> handle's method (easily done as the
|
|||
|
|
first argument to the existing call is the correct handle to use).</p>
|
|||
|
|
<p>In addition, the <a href="../api_reference/C/lockstat.html" class="olink">DB_ENV->lock_stat()</a> call has been changed in the 4.0
|
|||
|
|
release to take a flags argument. To leave their historic behavior
|
|||
|
|
unchanged, applications should add a final argument of 0 to any calls
|
|||
|
|
made to <a href="../api_reference/C/lockstat.html" class="olink">DB_ENV->lock_stat()</a>.</p>
|
|||
|
|
<p>The C++ and Java APIs for the DbLock::put (DbLock.put) method was
|
|||
|
|
reworked in the 4.0 release to make the lock put interface a method of
|
|||
|
|
the <a href="../api_reference/C/env.html" class="olink">DB_ENV</a> handle rather than the DbLock handle. Applications
|
|||
|
|
calling the DbLock::put or DbLock.put method should update their calls
|
|||
|
|
to use the enclosing <a href="../api_reference/C/env.html" class="olink">DB_ENV</a> handle's method (easily done as the
|
|||
|
|
first argument to the existing call is the correct handle to use).</p>
