ioctl FE_SET_FRONTEND_TUNE_MODE

Name

FE_SET_FRONTEND_TUNE_MODE - Allow setting tuner mode flags to the frontend.

Synopsis

.. c:macro:: FE_SET_FRONTEND_TUNE_MODE

int ioctl(int fd, FE_SET_FRONTEND_TUNE_MODE, unsigned int flags)

Arguments

fd File descriptor returned by :c:func: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.
