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);
