Typedef Documentation

typedef ibool(* pars_user_func_cb_t)(void *arg, void *user_arg)

Type of the user functions. The first argument is always InnoDB-supplied

and varies in type, while 'user_arg' is a user-supplied argument. The meaning of the return type also varies. See the individual use cases, e.g. the FETCH statement, for details on them.
