13 VIDIOC_S_HW_FREQ_SEEK - Perform a hardware frequency seek
37 zero out the ``reserved`` array of a struct
41 The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
42 to tell the driver to search a specific band. If the struct
45 within one of the bands returned by
48 must exactly match those of one of the bands returned by
50 current frequency of the tuner does not fall within the selected band it
51 will be clamped to fit in the band before the seek is started.
