[Discuss-gnuradio] gr_sync_block question

[Nowlan, Sean]

Do objects that extend gr_sync_block *require* that their work function *always* returns as many items as the scheduler asked in noutput_items, except for the case when a block may be completely finished producing items? What does the scheduler do if the (number of items returned) < noutput_items? Does it ever try calling the work function again?

 

Thanks,

Sean
