#include <db.h> DB_MULTIPLE_INIT(void *pointer, DBT *data);
If either of the DB_MULTIPLE or DB_MULTIPLE_KEY flags were specified to the DB->get() or DBcursor->get() methods, the data DBT returned by those interfaces will refer to a buffer that is filled with data. Access to that data is through the DB_MULTIPLE_* macros.
This macro initializes a variable used for bulk retrieval.
The data parameter is a DBT structure returned from a successful call to DB->get() or DBcursor->get() for which one of the DB_MULTIPLE or DB_MULTIPLE_KEY flags were specified.
