| Name | Description | |
|---|---|---|
 | MovePrevUnique()()() |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast()()(). Otherwise, move the cursor to the previous
non-duplicate key in the database, and store the secondary key and
primary key/data pair in Current. MovePrevUnique
returns false if no non-duplicate key/data pairs exist after the
cursor position in the database.
|
| MovePrevUnique(LockingInfo) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast(LockingInfo). Otherwise, move the cursor to
the previous non-duplicate key in the database, and store the
secondary key and primary key/data pair in Current.
MovePrevUnique returns false if no non-duplicate key/data pairs
exist after the cursor position in the database.
|
| MovePrevUnique(DatabaseEntry, DatabaseEntry, DatabaseEntry) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast()()(). Otherwise, move the cursor to the previous
non-duplicate key in the database, and store the secondary key and
primary key/data pair in Current. MovePrevUnique
returns false if no non-duplicate key/data pairs exist after the
cursor position in the database. If key, or
pkey, or data is
partial DatabaseEntry, its
PartialLen bytes starting
PartialOffset bytes from the beginning
of the retrieved data record are returned as if they comprised the
entire record. If any or all of the specified bytes do not exist
in the record, MovePrevUnique is successful, and any existing bytes
are returned.

| MovePrevUnique(DatabaseEntry, DatabaseEntry, DatabaseEntry, LockingInfo) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast(LockingInfo). Otherwise, move the cursor to
the previous non-duplicate key in the database, and store the
secondary key and primary key/data pair in Current.
MovePrevUnique returns false if no non-duplicate key/data pairs
exist after the cursor position in the database. If
key, or pkey, or
data is partial DatabaseEntry, its
PartialLen bytes starting
PartialOffset bytes from the beginning
of the retrieved data record are returned as if they comprised the
entire record. If any or all of the specified bytes do not exist
in the record, MovePrevUnique is successful, and any existing bytes
are returned.
