Reuse gr_ blocks

Hi all,

Is it possible to use the “gr_interp_fir_filter_fff” block directly
inside a
new block I am building in C++? Any example available on how to do it?

Thanks for your help,

Unless you were building a hierarchical block in C++ you wounldn’t use
anything derived from gr_block (or any of its subclasses) inside
another block.

You might however, want to use the gr_fir_fff primitive instead.

Take a look at gr_interp_fir_filter_fff.cc to see how it’s used, and
also read the comments in gr_fir_fff.h for important information on
its use.
