[Discuss-gnuradio] dynamically changing delay in gr_delay (or history in any gr_block) |

I made a simple example with a cosine and a delayed version of that
going through
a multiplier, and observing the output together with a slider that
changes the delay dynamically.
However i do not see any change (eg, elimination of the dc component
when delay ~ pi/2).
Looking at the code of the block gr_delay it shows that the delay can
dynamically change
and this results essentially in a call to set_history() in gr_block.
Looking further into the set_history() method, it sets the private
variable d_history.
The question is: does the dynamic change of history have any effect in gr_block?
What happens in the guts of the block when d_history changes?
and why don't i see any effect in the example above?
thanks
