<a class="link" href="dbput.html#put_DB_MULTIPLE">DB_MULTIPLE</a>
|

|

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.
