[Discuss-gnuradio] USRP v2 TX Bandwidth

[Gregory W. Heckler]

Is there a status indicator in the USRP2 C++ interface that flags 
underflows? I am trying to push samples (using the std::complex<int16_t> 
type) to the USRP2 at an interpolation factor of 4. It seems to be 
working, but I require hard evidence that I am not underflowing.
