[Discuss-gnuradio] callback function called twice

[Nemanja Savic]

Hi again GNURADIOers,

I have a set member function which is also used as a callback from GRC. It looks like this:

void
test_file_sink::set_sensitivity(double milisecond)
{
    d_n_samples = (unsigned int)(milisecond*d_sample_rate/1000.0)*d_itemsize;
  printf("\nd_n_samples: %d\n", d_n_samples);
    init_old_data_buff();
}

When I run flowgraph, and change "sensitivity", my callback function is called twice.

Is this normal action?

Best
