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 > .
