15.15.11. Implementing the index_prev() Function

The index_prev() function is used for reverse index scanning:

        int ha_foo::index_prev(byte * buf)

The *buf parameter is populated with the row that corresponds to the previous matching key value according to the internal cursor set by the storage engine during operations such as index_read() and index_last().
