[Discuss-gnuradio] GR Block Input Item Size

[Andrew Fong]

Hi,

I want to create a block that requires 10000 input items and produces 
10000 output items on a single stream.  However, I'm getting the 
following message: sched: <gr_block lfm_demod_cf (8)> is requesting more 
input data
  than we can provide.
  ninput_items_required = 10000
  max_possible_items_available = 8191
  If this is a filter, consider reducing the number of taps.

How do I get the block to operate as I want?  I thought inheriting from 
gr_sync_block with 1:1 input/output rate would work, but it doesn't 
seems to be the case.
