ioctl FE_DISEQC_RESET_OVERLOAD
******************************
Name
====
FE_DISEQC_RESET_OVERLOAD - Restores the power to the antenna subsystem, if it was powered off due - to power overload.
Synopsis
========
.. c:function:: int ioctl( int fd, FE_DISEQC_RESET_OVERLOAD, NULL )
:name: FE_DISEQC_RESET_OVERLOAD
Arguments
=========
``fd``
File descriptor returned by :ref:`open() <frontend_f_open>`.
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 Digital TV adapters support this ioctl.

============
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.
