Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
If the bus has been automatically powered off due to power overload,
|
||
|
|
this ioctl call restores the power to the bus. The call requires
|
||
|
|
read/write access to the device. This call has no effect if the device
|
||
|
|
is manually powered off. Not all DVB adapters support this ioctl.
|
||
|
|
|
||
|
|
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.
