Synopsis ======== .. c:macro:: FE_DISEQC_RESET_OVERLOAD ``int ioctl(int fd, FE_DISEQC_RESET_OVERLOAD, NULL)`` Arguments ========= ``fd`` File descriptor returned by :c:func:`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. Return Value ============ 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. |
