| 5377d91f | 11 | |
| 586027ce | 12 | FE_SET_FRONTEND_TUNE_MODE - Allow setting tuner mode flags to the frontend. |
| 5377d91f | 13 | |
| 586027ce | 14 | SYNOPSIS |
| 5377d91f MH |
15 | ======== |
| 16 | ||
| b7e67f6c | 17 | .. cpp:function:: int ioctl( int fd, int request, unsigned int flags ) |

| 20 | ARGUMENTS | |
| 5377d91f MH |
21 | ========= |
| 22 | ||
| 23 | ``fd`` | |
| 24 | File descriptor returned by :ref:`open() <frontend_f_open>`. | |
| 25 | ||
| 26 | ``request`` | |
| 27 | FE_SET_FRONTEND_TUNE_MODE | |
| 28 | ||
| 29 | ``flags`` | |
| 30 | Valid flags: | |
| 31 | ||
| 32 | - 0 - normal tune mode | |
| 33 | ||
| 34 | - FE_TUNE_MODE_ONESHOT - When set, this flag will disable any | |
| 35 | zigzagging or other "normal" tuning behaviour. Additionally, | |
| 36 | there will be no automatic monitoring of the lock status, and | |
| 37 | hence no frontend events will be generated. If a frontend device | |
| 38 | is closed, this flag will be automatically turned off when the | |
| 39 | device is reopened read-write. | |
| 40 | ||
| 41 | ||
| 586027ce | 42 | DESCRIPTION |
