33 File descriptor returned by :ref:`open() <frontend_f_open>`.
38 - 0 - normal tune mode
40 - ``FE_TUNE_MODE_ONESHOT`` - When set, this flag will disable any
41 zigzagging or other "normal" tuning behaviour. Additionally,
42 there will be no automatic monitoring of the lock status, and
43 hence no frontend events will be generated. If a frontend device
44 is closed, this flag will be automatically turned off when the
45 device is reopened read-write.
51 Allow setting tuner mode flags to the frontend, between 0 (normal) or
52 ``FE_TUNE_MODE_ONESHOT`` mode
58 On success 0 is returned.
