+FE_SET_PROPERTY - FE_GET_PROPERTY - FE_SET_PROPERTY sets one or more frontend properties. - FE_GET_PROPERTY returns one or more frontend properties.
+
+Synopsis
+========
+
+.. c:macro:: FE_GET_PROPERTY
+
+``int ioctl(int fd, FE_GET_PROPERTY, struct dtv_properties *argp)``
+
+.. c:macro:: FE_SET_PROPERTY
+
+``int ioctl(int fd, FE_SET_PROPERTY, struct dtv_properties *argp)``
+
+Arguments
+=========
+
+``fd``
+ File descriptor returned by :c:func:`open()`.
+
+``argp``
+ Pointer to struct :c:type:`dtv_properties`.
+
+Description
+===========
+
+All Digital TV frontend devices support the ``FE_SET_PROPERTY`` and
+``FE_GET_PROPERTY`` ioctls. The supported properties and statistics
+depends on the delivery system and on the device:
+
+- ``FE_SET_PROPERTY:``
+
+ - This ioctl is used to set one or more frontend properties.
+
+ - This is the basic command to request the frontend to tune into
+ some frequency and to start decoding the digital TV signal.
+
+ - This call requires read/write access to the device.
+
+.. note::
+
+ At return, the values aren't updated to reflect the actual
+ parameters used. If the actual parameters are needed, an explicit
+ call to ``FE_GET_PROPERTY`` is needed.
+
+- ``FE_GET_PROPERTY:``
+
+ - This ioctl is used to get properties and statistics from the
+ frontend.
+
+ - No properties are changed, and statistics aren't reset.
+
+ - This call only requires read-only access to the device.
+
+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.
