<p>
Initialize a DBT containing a bulk buffer for use with the
<a class="link" href="dbput.html#put_DB_MULTIPLE">DB_MULTIPLE</a>
or <a class="link" href="dbput.html#put_DB_MULTIPLE_KEY">DB_MULTIPLE_KEY</a>

<a class="xref" href="dbdel.html" title="DB->del()">DB->del()</a> methods, if the buffer
will contain record number keys.
</p>
<p>
This macro initializes an opaque pointer variable used for adding
records to a bulk buffer. Use this macro for buffers that will contain
either a list of record numbers (for use with
<a class="link" href="dbput.html#put_DB_MULTIPLE">DB_MULTIPLE</a>),
or key/data pairs, where the key is a record number.
