| 15e7d615 | 21 | Arguments |
| 5377d91f MH |
22 | ========= |
| 23 | ||
| 24 | ``fd`` | |
| 25 | File descriptor returned by :ref:`open() <frontend_f_open>`. | |
| 26 | ||
| 27 | ``request`` | |
| 28 | FE_SET_FRONTEND_TUNE_MODE | |
| 29 | ||
| 30 | ``flags`` | |
| 31 | Valid flags: | |
| 32 | ||
| 33 | - 0 - normal tune mode | |
| 34 | ||
| 35 | - FE_TUNE_MODE_ONESHOT - When set, this flag will disable any | |
| 36 | zigzagging or other "normal" tuning behaviour. Additionally, | |
| 37 | there will be no automatic monitoring of the lock status, and | |
| 38 | hence no frontend events will be generated. If a frontend device | |
| 39 | is closed, this flag will be automatically turned off when the | |
| 40 | device is reopened read-write. | |
