Re: [Discuss-gnuradio] Maximum input items consumed on each input stream

If you use set_output_multiple(), you don't have to check the input buffer. The block will only execute if there are a multiple of the value used in set_output_multiple() items available. For example, if set_output_multiple() is set to 256, the block will only execute if noutput_items is at least 256, but it could also be 512, 768, 1024, 1280, 1536, etc.

Since forecast() sets ninput_items_required to noutput_items, the same number of items appears on the input buffer.

Here's a dummy block that just copies input to output to show the structure. The loop in general_work() allows for any value of CHUNK_SIZE to work properly. With a size of 8900, the loop will typically only execute once.

#ifdef HAVE_CONFIG_H
#include "config.h"
