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. | |
