15.15.6. Preparing for Index Use with index_init()

The index_init() function is called before an index is used to allow the storage engine to perform any necessary preparation or optimization:

int ha_foo::index_init(uint keynr, bool sorted)

Most storage engines do not need to make special preparations, in which case a default implementation will be used if the method is not explicitly implemented in the storage engine:

int handler::index_init(uint idx) { active_index=idx; return 0; }
