| 11 | Restores the power to the antenna subsystem, if it was powered off due | |
| 12 | to power overload. | |

| 15 | Synopsis | |
| 16 | ======== | |

| 18 | .. c:function:: int ioctl( int fd, int request, NULL ) | |
| 19 | ||
| 20 | Arguments | |
| 21 | ========= | |
| 22 | ||

| 30 | Description | |
| 31 | =========== | |
| 32 | ||
| 33 | If the bus has been automatically powered off due to power overload, | |
| 34 | this ioctl call restores the power to the bus. The call requires | |
| 35 | read/write access to the device. This call has no effect if the device | |
| 36 | is manually powered off. Not all DVB adapters support this ioctl. | |
| 37 | ||
| 38 | RETURN VALUE | |
| 39 | ||
| 40 | On success 0 is returned, on error -1 and the ``errno`` variable is set | |
| 41 | appropriately. The generic error codes are described at the | |
| 42 | :ref:`Generic Error Codes <gen-errors>` chapter. | |
