I'm working with the ns3 program, and trying to understand the code I have at hand, I came across this line, and would like to know what this sequence of "< means (I am not referring to the variables, but to the command "< <")
I read about it and found this: it shifts to the left and adds zeros at the right end, but this is true between 2 values. I do not know what chained mode means as shown in the function below.
NS_LOG_FUNCTION (this << tcb << packetsAcked << rtt);
