int move_to(const kdt &k,
int flag=DB_SET) const
Iterator movement function.
Move this iterator to the specified key k, by default moves exactly to k, and update cached data element, you can also specify DB_SET_RANGE, to move to the biggest key smaller than k. The btree/hash key comparison routine determines which key is bigger. When the iterator is on a multiple container, move_to will move itself to the first key/data pair of the identical keys.
