	DatabaseEntry key,
	DatabaseEntry data,
	int BufferSize,
	Transaction txn
)
Visual Basic (Declaration)

KeyValuePair<DatabaseEntry^, MultipleDatabaseEntry^> GetBothMultiple(
	DatabaseEntry^ key, 
	DatabaseEntry^ data, 
	int BufferSize, 
	Transaction^ txn
)

Parameters

key
Type: BerkeleyDB..::.DatabaseEntry
The key to search for
data
Type: BerkeleyDB..::.DatabaseEntry
The data to search for
BufferSize
Type: System..::.Int32
The initial size of the buffer to fill with duplicate data items. If the buffer is not large enough, it is automatically resized.
txn
Type: BerkeleyDB..::.Transaction
txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.
