[Discuss-gnuradio] Question on rx_streaming_samples/libursp2

[Per Zetterberg]

Hi,

(I am using the VRT code but I don't think it matters for the questions 
below)

In rx_streaming_samples.cc one finds the following code:


while (!signaled &&
        !handler->has_errored_p() &&
        !handler->has_finished_p()) {
   bool ok = u2->rx_samples(handler.get());
   if (!ok){
     fprintf(stderr, "u2->rx_samples failed\n");
     return 1;
   }
 }

Does every call of u2->rx_samples(handler.get()) result in one call of 
e.g. file_writer_32fc ?

Is there any way of receiving samples from the usrp2 that doesn't 
involve calling "start_rx_streaming" ?
