| 14 | Synopsis | |
| 15 | ======== | |
| 16 | ||
| 17 | .. c:function:: int ioctl( int fd, int request, unsigned int flags ) | |
| 18 | ||
| 19 | Arguments | |
| 20 | ========= | |
| 21 | ||
| 22 | ``fd`` | |
| 23 | File descriptor returned by :ref:`open() <frontend_f_open>`. | |
| 24 | ||
| 25 | ``request`` | |
| 26 | FE_SET_FRONTEND_TUNE_MODE | |
| 27 | ||
| 28 | ``flags`` | |
| 29 | Valid flags: | |
| 30 | ||
| 31 | - 0 - normal tune mode | |
| 32 | ||
| 33 | - FE_TUNE_MODE_ONESHOT - When set, this flag will disable any | |
| 34 | zigzagging or other "normal" tuning behaviour. Additionally, | |
| 35 | there will be no automatic monitoring of the lock status, and | |
| 36 | hence no frontend events will be generated. If a frontend device | |
| 37 | is closed, this flag will be automatically turned off when the | |
| 38 | device is reopened read-write. | |
| 39 | ||
| 40 | ||
| 41 | Description | |
| 42 | =========== | |
| 43 | ||
| 44 | Allow setting tuner mode flags to the frontend, between 0 (normal) or | |
| 45 | FE_TUNE_MODE_ONESHOT mode | |
| 46 | ||
| 47 | RETURN VALUE | |
| 48 | ||
| 49 | On success 0 is returned, on error -1 and the ``errno`` variable is set | |
| 50 | appropriately. The generic error codes are described at the | |
| 51 | :ref:`Generic Error Codes <gen-errors>` chapter. | |
