15.14.1. Implementing the position() Function

The position() function is called after every call to rnd_next() if the data needs to be reordered:

void ha_foo::position(const byte *record)

The contents of *record are up to you — whatever value you provide will be returned in a later call to retrieve the row. Most storage engines will store some form of offset or primary key value.
