- ``int ioctl(int fd, FE_SET_FRONTEND_TUNE_MODE, unsigned int flags)``
- Arguments
- =========
- ``fd``
- File descriptor returned by :c:func:`open()`.
- ``flags``
- Valid flags:

- zigzagging or other "normal" tuning behaviour. Additionally,
- there will be no automatic monitoring of the lock status, and
- hence no frontend events will be generated. If a frontend device
- is closed, this flag will be automatically turned off when the
- device is reopened read-write.

- ``FE_TUNE_MODE_ONESHOT`` mode
- Return Value
- ============

- On error -1 is returned, and the ``errno`` variable is set
- appropriately.

- :ref:`Generic Error Codes <gen-errors>` chapter.
