|
|
|
-- Master: broadcast -item-
|
|
|
|
|
-- matching slave: send -ack- or -empty-
|
|
|
|
|
-- in case of a -ack- the master will wait for -return-
|
|
|
|
|
-- in case of -empty- the master will exit
|

|
|
|
|
|
|
|
|
-- if there is no matching slave, then the master won't receive ack and exits
|
|
|
|
|
-- if there are more matching slaves, then there is UB
