15.9.5. Implementing the extra() Function

Prior to some operations, the extra() function is called to provide extra hints to the storage engine on how to perform certain operations.

Implementation of the hints in the extra call is not mandatory, and most storage engines return 0:

int ha_tina::extra(enum ha_extra_function operation)
{
   DBUG_ENTER("ha_tina::extra");
   DBUG_RETURN(0);
}
