Hi All,

As usual, I have a simple question for you guys. I have a custom block for which I specify set_output_multiple(N) in the constructor. Then, for each call to its work(), I print the parameter noutput_items. As expected, noutput_items = N most of the times, but occasionally it comes out as 2N. My concern is that I always want noutput_items = N. I know noutput_items are assigned by the scheduler and I have a some control over it by means of set_output_multiple but I want to have more/full control on it. Is that possible? Any suggestions?



You don't always have to consume everything that's handed to you. So if you get kN items, just process N of them, return N, then the scheduler will pass you the next N items in the buffer next time.
