+
+FE_SET_FRONTEND_TUNE_MODE - Allow setting tuner mode flags to the frontend.
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, FE_SET_FRONTEND_TUNE_MODE, unsigned int flags )
+    :name: FE_SET_FRONTEND_TUNE_MODE
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <frontend_f_open>`.
+
+``flags``
+    Valid flags:
+
+    -  0 - normal tune mode
+
+    -  ``FE_TUNE_MODE_ONESHOT`` - When set, this flag will disable any
+       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.
+
+
+Description
+===========
+
+Allow setting tuner mode flags to the frontend, between 0 (normal) or
+``FE_TUNE_MODE_ONESHOT`` mode
+
+
+Return Value
+============
+
+On success 0 is returned.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.
+
+Generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
