XkbSetIgnoreLockMods(3)		 XKB FUNCTIONS	       XkbSetIgnoreLockMods(3)

       XkbSetIgnoreLockMods  -	Sets the modifiers that, if locked, are	not to
       be reported in matching events to passive grabs

       Bool XkbSetIgnoreLockMods (Display *display, unsigned int  device_spec,
	      unsigned int affect_real,	unsigned int real_values, unsigned int
	      affect_virtual, unsigned int virtual_values);

       - display
	      connection to the	X server

       - device_spec
	      device ID, or XkbUseCoreKbd

       - affect_real
	      mask of real modifiers affected by this call

       - real_values
	      values for affected real modifiers (1=>set, 0=>unset)

       - affect_virtual
	      mask of virtual modifiers	affected by this call

       - virtual_values
	      values for affected virtual modifiers (1=>set, 0=>unset)

       The core	protocol does not provide a way	to exclude specific  modifiers
       from  grab  calculations,  with the result that locking modifiers some-
       times have unanticipated	side effects.

       The IgnoreLockMods control specifies modifiers that should be  excluded
       from  grab  calculations.  These	modifiers are also not reported	in any
       core events except KeyPress and KeyRelease events that do not  activate
       a passive grab and that do not occur while a grab is active.

       Manipulate  the IgnoreLockMods control via the ignore_lock field	in the
       XkbControlsRec structure, then use XkbSetControls and XkbGetControls to
       query and change	this control. Alternatively, use XkbSetIgnoreLockMods.

       XkbSetIgnoreLockMods  sends  a  request	to  the	 server	 to change the
       server's	IgnoreLockMods control.	 affect_real and real_values are masks
       of  real	 modifier bits indicating which	real modifiers are to be added
       and removed from	the server's  IgnoreLockMods  control.	Modifiers  se-
       lected  by  both	 affect_real and real_values are added to the server's
       IgnoreLockMods control;	those  selected	 by  affect_real  but  not  by
       real_values are removed from the	server's IgnoreLockMods	control. Valid
       values for affect_real and real_values consist of  any  combination  of
       the   eight  core  modifier  bits:  ShiftMask,  LockMask,  ControlMask,
       Mod1Mask	- Mod5Mask.  affect_virtual and	virtual_values	are  masks  of
       virtual	modifier  bits	indicating  which  virtual modifiers are to be
       added and removed from the server's IgnoreLockMods  control.  Modifiers
       selected	 by  both  affect_virtual  and virtual_values are added	to the
       server's	IgnoreLockMods control;	those selected by  affect_virtual  but
       not by virtual_values are removed from the server's IgnoreLockMods con-
       trol. See below for a discussion	of virtual modifier masks  to  use  in
       affect_virtual  and  virtual_values. XkbSetIgnoreLockMods does not wait
       for a reply from	the server. It returns True if the request  was	 sent,
       and False otherwise.

       Virtual	modifiers  are	named  by converting their string name to an X
       Atom and	storing	the Atom in the	names.vmods  array  in	an  XkbDescRec
       structure. The position of a name Atom in the names.vmods array defines
       the bit position	used to	represent the virtual modifier	and  also  the
       index  used  when accessing virtual modifier information	in arrays: the
       name in the i-th	(0 relative) entry of names.vmods is the i-th  virtual
       modifier, represented by	the mask (1<<i). Throughout Xkb, various func-
       tions have a parameter that is a	 mask  representing  virtual  modifier
       choices.	In each	case, the i-th bit (0 relative)	of the mask represents
       the i-th	virtual	modifier.

       To set the name of a virtual modifier, use XkbSetNames,	using  XkbVir-
       tualModNamesMask	in which and the name in the xkb argument; to retrieve
       indicator names,	use XkbGetNames.

       The complete description	of an Xkb keyboard is given by an  XkbDescRec.
       The component structures	in the XkbDescRec represent the	major Xkb com-

       typedef struct {
	   struct _XDisplay * display;	    /* connection to X server */
	   unsigned short     flags;	    /* private to Xkb, do not modify */
	   unsigned short     device_spec;  /* device of interest */
	   KeyCode	      min_key_code; /* minimum keycode for device */
	   KeyCode	      max_key_code; /* maximum keycode for device */
	   XkbControlsPtr     ctrls;	    /* controls	*/
	   XkbServerMapPtr    server;	    /* server keymap */
	   XkbClientMapPtr    map;	    /* client keymap */
	   XkbIndicatorPtr    indicators;   /* indicator map */
	   XkbNamesPtr	      names;	    /* names for all components	*/
	   XkbCompatMapPtr    compat;	    /* compatibility map */
	   XkbGeometryPtr     geom;	    /* physical	geometry of keyboard */
       } XkbDescRec, *XkbDescPtr;

       The display field points	to an X	display	structure. The flags field  is
       private	to  the	 library:  modifying flags may yield unpredictable re-
       sults. The device_spec field specifies the  device  identifier  of  the
       keyboard	 input device, or XkbUseCoreKeyboard, which specifies the core
       keyboard	device.	The min_key_code and max_key_code fields  specify  the
       least and greatest keycode that can be returned by the keyboard.

       Each  structure	component has a	corresponding mask bit that is used in
       function	calls to indicate that the structure should be manipulated  in
       some manner, such as allocating it or freeing it. These masks and their
       relationships to	the fields in the XkbDescRec are shown in Table	1.
