**Members** ``node`` The list node. ``ev_subs`` The list of control event subscriptions. ``handler`` The handler that owns the control. ``cluster`` Point to start of cluster array. ``ncontrols`` Number of controls in cluster array. ``done`` Internal flag: set for each processed control. ``is_new`` Set when the user specified a new value for this control. It is also set when called from v4l2_ctrl_handler_setup(). Drivers should never set this flag. ``has_changed`` Set when the current value differs from the new value. Drivers should never use this flag. ``is_private`` If set, then this control is private to its handler and it will not be added to any other handlers. Drivers can set this flag. ``is_auto`` If set, then this control selects whether the other cluster members are in 'automatic' mode or 'manual' mode. This is used for autogain/gain type clusters. Drivers should never set this flag directly. ``is_int`` If set, then this control has a simple integer value (i.e. it uses ctrl->val). ``is_string`` If set, then this control has type ``V4L2_CTRL_TYPE_STRING``. ``is_ptr`` If set, then this control is an array and/or has type >= ``V4L2_CTRL_COMPOUND_TYPES`` and/or has type ``V4L2_CTRL_TYPE_STRING``. In other words, :c:type:`struct v4l2_ext_control ` uses field p to point to the data. ``is_array`` If set, then this control contains an N-dimensional array. ``is_dyn_array`` If set, then this control contains a dynamically sized 1-dimensional array. If this is set, then **is_array** is also set. ``has_volatiles`` If set, then one or more members of the cluster are volatile. Drivers should never touch this flag. ``call_notify`` If set, then call the handler's notify function whenever the control's value changes. ``manual_mode_value`` If the is_auto flag is set, then this is the value of the auto control that determines if that control is in manual mode. So if the value of the auto control equals this value, then the whole cluster is in manual mode. Drivers should never set this flag directly. ``ops`` The control ops. ``type_ops`` The control type ops. ``id`` The control ID. ``name`` The control name. ``type`` The control type. ``minimum`` The control's minimum value. ``maximum`` The control's maximum value. ``default_value`` The control's default value. ``elems`` The number of elements in the N-dimensional array. ``elem_size`` The size in bytes of the control. ``new_elems`` The number of elements in p_new. This is the same as **elems**, except for dynamic arrays. In that case it is in the range of 1 to **p_array_alloc_elems**. ``dims`` The size of each dimension. ``nr_of_dims`` The number of dimensions in **dims**. ``{unnamed_union}`` anonymous ``step`` The control's step value for non-menu controls. ``menu_skip_mask`` The control's skip mask for menu controls. This makes it easy to skip menu items that are not valid. If bit X is set, then menu item X is skipped. Of course, this only works for menus with <= 32 menu items. There are no menus that come close to that number, so this is OK. Should we ever need more, then this will have to be extended to a u64 or a bit array. ``{unnamed_union}`` anonymous ``qmenu`` A const char * array for all menu items. Array entries that are empty strings ("") correspond to non-existing menu items (this is in addition to the menu_skip_mask above). The last entry must be NULL. Used only if the **type** is ``V4L2_CTRL_TYPE_MENU``. ``qmenu_int`` A 64-bit integer array for with integer menu items. The size of array must be equal to the menu size, e. g.: :math:`ceil(\frac{maximum - minimum}{step}) + 1`. Used only if the **type** is ``V4L2_CTRL_TYPE_INTEGER_MENU``. ``flags`` The control's flags. ``priv`` The control's private pointer. For use by the driver. It is untouched by the control framework. Note that this pointer is not freed when the control is deleted. Should this be needed then a new internal bitfield can be added to tell the framework to free this pointer. ``p_array`` Pointer to the allocated array. Only valid if **is_array** is true. ``p_array_alloc_elems`` The number of elements in the allocated array for both the cur and new values. So **p_array** is actually sized for 2 * **p_array_alloc_elems** * **elem_size**. Only valid if **is_array** is true. ``val`` The control's new s32 value. ``cur`` Structure to store the current value. ``cur.val`` The control's current value, if the **type** is represented via a u32 integer (see :c:type:`enum v4l2_ctrl_type `). ``p_def`` The control's default value represented via a union which provides a standard way of accessing control types through a pointer (for compound controls only). ``p_min`` The control's minimum value represented via a union which provides a standard way of accessing control types through a pointer (for compound controls only). ``p_max`` The control's maximum value represented via a union which provides a standard way of accessing control types through a pointer (for compound controls only). ``p_new`` The control's new value represented via a union which provides a standard way of accessing control types through a pointer. ``p_cur`` The control's current value represented via a union which provides a standard way of accessing control types through a pointer.h](j)}(hX **Definition**:: struct v4l2_ctrl { struct list_head node;

**Members** ``node`` List node for the sorted list. ``next`` Single-link list node for the hash. ``ctrl`` The actual control information. ``helper`` Pointer to helper struct.

controls in this cluster. ``struct v4l2_ctrl **controls`` The cluster control array of size **ncontrols**. The first control must be the 'auto' control (e.g. autogain, autoexposure, etc.) ``u8 manual_val`` The value for the first control in the cluster that equals the manual setting. ``bool set_volatile`` If true, then all controls except the first auto control will be volatile. **Description** Use for control groups where one control selects some automatic feature and the other controls are only active whenever the automatic feature is turned off (manual mode). Typical examples: autogain vs gain, auto-whitebalance vs red and blue balance, etc. The behavior of such controls is as follows: When the autofoo control is set to automatic, then any manual controls are set to inactive and any reads will call g_volatile_ctrl (if the control was marked volatile). When the autofoo control is set to manual, then any manual controls will be marked active, and any reads will just return the current value without going through g_volatile_ctrl. In addition, this function will set the ``V4L2_CTRL_FLAG_UPDATE`` flag on the autofoo control and ``V4L2_CTRL_FLAG_INACTIVE`` on the foo control(s) if autofoo is in auto mode.h](h)}(h**Parameters**h]j)}(hjBuh]h Parameters}(hjDuhhhNhNubah}(h]h ]h"]h$]h&]uh1jhj@uubah}(h]h ]h"]h$]h&]uh1hhj/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-controls:820: ./include/media/v4l2-ctrls.hhMNhjhjvhhhjwhMnubh)}(hhh]jV)}(h v4l2_ctrlh]h v4l2_ctrl}(hj whhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhjwubah}(h]h ]h"]h$]h&] refdomainjreftypej reftargetj"wmodnameN classnameNjj)}j]j)}jv4l2_ctrl_findsbc.v4l2_ctrl_findasbuh1hhjvhhhjwhMnubj?)}(h h]h }(hjAwhhhNhNubah}(h]h ]jKah"]h$]h&]uh1j>hjvhhhjwhMnubj)}(hjh]h*}(hjOwhhhNhNubah}(h]h ]jah"]h$]h&]uh1jhjvhhhjwhMnubjP)}(hv4l2_ctrl_findh]jV)}(hj>wh]hv4l2_ctrl_find}(hj`whhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhj\wubah}(h]h ](jhjieh"]h$]h&]hhuh1jOhjvhhhjwhMnubj)}(h'(struct v4l2_ctrl_handler *hdl, u32 id)h](j)}(hstruct v4l2_ctrl_handler *hdlh](j-)}(hjh]hstruct}(hj{whhhNhNubah}(h]h ]j9ah"]h$]h&]uh1j,hjwwubj?)}(h h]h }(hjwhhhNhNubah}(h]h ]jKah"]h$]h&]uh1j>hjwwubh)}(hhh]jV)}(hv4l2_ctrl_handlerh]hv4l2_ctrl_handler}(hjwhhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhjwubah}(h]h ]h"]h$]h&] refdomainjreftypej reftargetjwmodnameN classnameNjj)}j]jhjwwubj)}(hjh]h*}(hjwhhhNhNubah}(h]h ]jah"]h$]h&]uh1jhjwwubjV)}(hhdlh]hhdl}(hjwhhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhjwwubeh}(h]h ]h"]h$]h&]noemphhhuh1jhjswubj)}(hu32 idh](h)}(hhh]jV)}(hu32h]hu32}(hjwhhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhjwubah}(h]h ]h"]h$]h&] refdomainjreftypej reftargetjwmodnameN classnameNjj)}j]jhjwubjV)}(hidh]hid}(hjxhhhNhNubah}(h]h ]jaah"]h$]h&]uh1jUhjwubeh}(h]h ]h"]h$]h&]noemphhhuh1jhjswubeh}(h]h ]h"]h$]h&]hhuh1jhjvhhhjwhMnubeh}(h]h ]h"]h$]h&]hhjsuh1j&jtjuhjvhhhjwhMnubah}(h]jvah ](jyjzeh"]h$]h&]j~j)jhuh1j hjwhMnhjvhhubj)}(hhh]h)}(h!Find a control with the given ID.h]h!Find a control with the given ID.}(hjDxhhhNhNubah}(h]h ]h"]h$]h&]uh1hhj/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-controls:820: ./include/media/v4l2-ctrls.hhMnhjAxhhubah}(h]h ]h"]h$]h&]uh1jhjvhhhjwhMnubeh}(h]h ](jfunctioneh"]h$]h&]jjjj\xjj\xjjjuh1jhhhj hNhNubj)}(h**Parameters** ``struct v4l2_ctrl_handler *hdl`` The control handler. ``u32 id`` The control ID to find. **Description** If **hdl** == NULL this will return NULL as well.
