Vector sink

What’s the intended usage for a “Vector Sink”? I have the output vector
(after complex-to-mag, and IIR filtering) of an FFT, and I want to
pick out specfic subsets of bins, and do stuff with them.

The vector sinks are not meant for “production” code, but for simple
tests
scripts. If you need to continuously get data out of a flow graph, the
best
approach is to use a message sink and have a thread that reads the
message
queue until another message is posted, then you do what you want with
the
returned data from there.

This is how we get data out of the digital modulation examples.

Thanks, Tom. I figured this out a little while ago.
