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> flags to the <a class="xref" href="dbput.html" title="DB->put()">DB->put()</a> or <a class="xref" href="dbdel.html" title="DB->del()">DB->del()</a> methods.
</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 data item per record (for use with
<a class="link" href="dbput.html#put_DB_MULTIPLE">DB_MULTIPLE</a>),
or key/data pairs, where the key is not a record number. For record
number keys, use <a class="link" href="DB_MULTIPLE_RECNO_WRITE_INIT.html" title="DB_MULTIPLE_RECNO_WRITE_INIT">DB_MULTIPLE_RECNO_WRITE_INIT</a>.
