[Discuss-gnuradio] Suppressing UHD prints

[Piotr Krysik]

Hi all,

UHD host library generates prints on the stdout. For example on each
retune I get something like:

-- Tune Request: 959.000000 MHz
--   The RF LO does not support the requested frequency:
--     Requested LO Frequency: 959.000000 MHz
--     RF LO Result: 958.998779 MHz
--   Attempted to use the DSP to reach the requested frequency:
--     Desired DSP Frequency: -0.001221 MHz
--     DSP Result: -0.001221 MHz
--   Successfully tuned to 959.000000 MHz
-- 

These prints are sometimes cluttering the console - especially when
someone wants to use console to print other useful information.

There is possibility to disable them in UHD from the level of C++:

("Disabling or redirecting prints to stdout")

Is it possible to disable the prints from GNU Radio?
