15.15.9. Implementing the index_read_idx() Function

The index_read_idx() function is identical to the index_read() with the exception that index_read_idx() accepts an additional keynr parameter:

int ha_foo::index_read_idx(byte * buf, uint keynr, const byte * key,
                        uint key_len, enum ha_rkey_function find_flag)  

The keynr parameter specifies the index to be read, as opposed to index_read where the index is already set.

As with the index_read() function, the storage engine must return the row that matches the key according to the find_flag and set a cursor for future reads.
