<p class=MsoNormal>Following text snippet is from oracle website for bdb.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:36.0pt'>When partial keys are specified
to Berkeley DB, interfaces which retrieve data items based on a user-specified
key (for example, <a
href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/db_get.html">DB->get</a>
and <a
href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/dbc_get.html">DBcursor->get</a>
with the <a
href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/dbc_get.html#DB_SET">DB_SET</a>
flag), <b><span style='color:red'>[[ will modify the user-specified key by
returning the actual key stored in the database ]]</span></b>.<o:p></o:p></p>

<p class=MsoNormal style='margin-left:36.0pt'><o:p> </o:p></p>
<p class=MsoNormal>My curiosity is that, how can we return data from DB_get
function while updating partial key with actual returned key.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>How can we update the passed parameter for key (keyobj)
rather than re-assigning new object using BuildValue_* functions?<o:p></o:p></p>
