int work(int noutput_items, gr_vector_const_void_star &input_items, gr_vector_void_star &output_items)
iq_sink_impl(const float scale, const char *filename, bool append, const int status)
This block converts a complex float input stream to short and stores it to a file. If the value of status argument is zero the block behaves as a null sink block.
