<h1 align=center>Release 3.0: DB_RMW</h1>
18
<p>The following change applies only to applications using the
19
Berkeley DB Concurrent Data Store product. If your application is not using that product,
20
you can ignore this change.
21
<p>Historically, the Berkeley DB <a href="../../api_c/db_cursor.html">DB->cursor</a> interface took the DB_RMW flag
22
to indicate that the created cursor would be used for write operations on
23
the database. This flag has been renamed to the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a>
25
<p>The application should be searched for any occurrences of DB_RMW. For
26
each of these, any that are arguments to the <a href="../../api_c/db_cursor.html">DB->cursor</a> function
27
should be changed to pass in the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> flag instead.
