You can create a named pipe with mkfifo /tmp/fifo. Connect your gnuradio stream to a gr.file_sink(item_size, '/tmp/fifo'). And in your c++ program, you can read from the fifo just like a regular file.

Can anyone please help me?

I want to capture samples from Gnuradio and get them to a c++
application in real-time.  I then want to calculate the ambiguity
function and display it on a contour plot.  What is the best way to do
this?  What I have in mind is to use Qwt with Qt for this, but then I
will need to get the samples to c++ in real-time.

Thank you very much.
