Having different output item numbers on different ports gnuradio

I have a block which has two output ports in gnuradio. I need to return a single items to one output port and some specific n output items on another output port. Is this possible or always it returns same number of items on different ports

It's possible. gr::block has a method called produce(int,int) to allow you to do exactly that. You'll have to return WORK_CALLED_PRODUCE instead of returning a number of samples.

Of course, not producing the same amount on all outputs means that you can't use sync_block and quite likely will have to implement a forecast() too.
