A quick look at the documentation or code will reveal that these
functions return a bool for success or failure, and the actual value
by reference:
http://gnuradio.org/doc/doxygen/classusrp2_1_1usrp2.html
// Get Sampling rate of A/D converter in Hz
bool adc_rate(long *rate);
// Get Sampling rate of D/A converter in Hz
bool dac_rate(long *rate);
