  18 .. cpp:function:: int ioctl( int fd, int request, unsigned int flags )

  21 Arguments
  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.
