Description |
|
=========== |
|
|
|
.. warning:: |
|
This is a very obscure legacy command, used only at stv0299 |
|
driver. 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. |
|
|
|

|
============ |
|
|
|
On success 0 is returned. |
|
|
|
On error -1 is returned, and the ``errno`` variable is set |
|
appropriately. |
|

Generic error codes are described at the |
|
:ref:`Generic Error Codes <gen-errors>` chapter.
