Gr_block: history

Hello,

a quick question regarding gr_block::history() etc.

Say I’ve called set_history(2) in the constructor and
my work function pointers look like this:

gr_complex const *in = (const gr_complex *) input_items[0];
gr_complex *out = (gr_complex *) output_items[0];

What does “in” point to? Is the item “in” points to already processed,
as the name history suggests? Or does it just assure that there are at
least
2 items in “input_items”?

set_history impacts the result computed by forecast. Take a look at
that code.
