15.14.2. Implementing the rnd_pos() Function

The rnd_pos() function behaves in a similar fashion to the rnd_next() function but takes an additional parameter:

int ha_foo::rnd_pos(byte * buf, byte *pos)

The *pos parameter contains positioning information previously recorded using the position() function.

A storage engine must locate the row specified by the position and return it through *buf in the internal MySQL row format.
