I'm having difficulty with a block I'm writing that I've been

The block's input and output run at different rates, so I
inherited from gr_block, as in the howto-write-a-block-3.1.1
first example. In addition, I supplied a forecast method
that returns the number of input items required for a given
number of output items, and I used the
"set_relative_rate" method in the constructor to set
the relative rate to output_rate/input_rate.
BTW, is the input rate to output rate relationship constant?
E.g., 1:N or N:1. If so, you can use the gr_sync_interpolator or
gr_sync_decimator base class. Less likelihood of trouble with those ;)
