[help!!!!]how can i get to know the messages (using the send(msgs, timeout) func) have been successfully acked on the CANBUS? #1819

for example, i send msgs in a very high frequency, but i dont know if the msg i send successfully acked on the can bus.
i try to send next message after the previous message has been acked by the can bus
