description, what does this structure represents?

[maksims (do not use this acc), 2016/10/19 06:57:09]

Done.

+  // Provides a base path to all sensors.
+  const base::FilePath::CharType* base_path_sensor_iio;
+  // Provides an array of sensor file names to be searched for.
+  const char** sensor_file_names[3];
+  // Number of words in one set.

[Mikhail, 2016/10/18 11:37:20]

could you give more concrete description? i.e. "number of sensor files" or smth
like that

[maksims (do not use this acc), 2016/10/19 06:57:09]

Done.

+  size_t sensor_file_names_cols;
+  // Number of arrays of words.

ditto. "corresponds to the sensor reading fields number"

[maksims (do not use this acc), 2016/10/19 06:57:09]

Done.
