Iterates over individual event operations making up the current
global checkpoint. Use following
nextEvent2() to obtain
summary information for the epoch, such as a listing of all
tables, before processing event data.
Exceptional epochs do not have any event operations associated with them.
const NdbEventOperation* getNextEventOpInEpoch2 ( Uint32* iter, Uint32* event_types )
iter to 0 initially; this is
NULL when there are no more events
within this epoch. If
NULL, it holds a bitmask of the
event types received.
