Typedef Documentation

latch_meta_t

typedef LatchMeta<LatchCounter> latch_meta_t

LatchMetaData

typedef std::vector<latch_meta_t *, ut::allocator<latch_meta_t *> > LatchMetaData

rw_lock_flags_t

typedef ulint rw_lock_flags_t

Enumeration Type Documentation

latch_id_t

enum latch_id_t

Each latch has an ID.

This id is used for creating the latch and to look up its meta-data. See sync0debug.c. The order does not matter here, but alphabetical ordering seems useful
