   6 Querying frontend status and statistics

   9 Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
  10 frontend will run a kernel thread that will periodically check for the
  11 tuner lock status and provide statistics about the quality of the
  12 signal.
  13
  14 The information about the frontend tuner locking status can be queried
  15 using :ref:`FE_READ_STATUS`.
  16
  17 Signal statistics are provided via
  18 :ref:`FE_GET_PROPERTY`. Please note that several
  19 statistics require the demodulator to be fully locked (e. g. with
  20 FE_HAS_LOCK bit set). See
  21 :ref:`Frontend statistics indicators <frontend-stat-properties>` for
  22 more details.
