I created a C++ block using gr_modtool in which I declared one variable
the argument list initially. I now want to update this block to take
arguments. What is the recommended way of going about this?
My current flow in this situation is to start over. Make a new block
gr_modtool and copy paste the existing code into the new block files
updates to the arguments. This is error prone.
How do you experienced developers handle this?
