Should not be used on newer drivers. + +It provides a non-standard method for selecting Diseqc voltage on the +frontend, for Dish Network legacy switches. + +As support for this ioctl were added in 2004, this means that such +dishes were already legacy in 2004. + + +Return Value +============ + +On success 0 is returned, on error -1 and the ``errno`` variable is set +appropriately. The generic error codes are described at the +:ref:`Generic Error Codes <gen-errors>` chapter. |
