XkbChangeEnabledControls(3)		  XKB FUNCTIONS 	      XkbChangeEnabledControls(3)

NAME
       XkbChangeEnabledControls - Manipulates the EnabledControls control

SYNOPSIS
       Bool  XkbChangeEnabledControls (Display *dpy, unsigned int device_spec, unsigned int mask,
	      unsigned int values);

ARGUMENTS
       - dpy  connection to X server

       - device_spec
	       keyboard device to modify

       - mask 1 bit -> controls to enable / disable

       - values
	      1 bit => enable, 0 bit => disable

DESCRIPTION
       The EnabledControls control is a bit mask where each bit that is turned on means the  cor-
       responding  control  is	enabled,  and  when  turned  off, disabled. It corresponds to the
       enabled_ctrls field of an XkbControlsRec structure (see STRUCTURES). The  bits  describing
       which controls are turned on or off are defined in Table 1.

       Table  1  shows the actual values for the individual mask bits used to select controls for
       modification and to enable and disable the control. Note that the same mask bit is used to
       specify general modifications to the parameters used to configure the control (which), and
       to enable and disable the control (enabled_ctrls). The anomalies in the table (no "ok"  in
       column)	are  for controls that have no configurable attributes; and for controls that are
       not boolean controls and therefore cannot be enabled or disabled.

			       Table 1 Controls Mask Bits

       XkbOverlay2Mask				ok	  (1L<<11)

       XkbIgnoreLockModsMask	ok			  (1L<<29)
       XkbPerKeyRepeatMask	ok			  (1L<<30)
       XkbControlsEnabledMask	ok			  (1L<<31)
       XkbAccessXOptionsMask	ok		ok	  (XkbStickyKeysMask |
							  XkbAccessXFeedbackMask)
       XkbAllBooleanCtrlsMask			ok	  (0x00001FFF)
       XkbAllControlsMask	ok			  (0xF8001FFF)

       The mask parameter specifies the boolean controls to be enabled or disabled, and the  val-
       ues  mask specifies the new state for those controls. Valid values for both of these masks
       are composed of a bitwise inclusive OR of bits taken from the set of mask bits in Table 1,
       using only those masks with "ok" in the enabled_ctrls column.

       If  the X server does not support a compatible version of Xkb or the Xkb extension has not
       been properly initialized, XkbChangeEnabledControls returns False; otherwise, it sends the
       request to the X server and returns True.

       Note that the EnabledControls control only enables and disables controls; it does not con-
       figure them. Some controls,  such  as  the  AudibleBell	control,  have	no  configuration
       attributes  and	are  therefore manipulated solely by enabling and disabling them. Others,
       however, have additional attributes to configure their behavior. For example, the  Repeat-
       Control control uses repeat_delay and repeat_interval fields to describe the timing behav-
       ior of keys that repeat. The RepeatControl behavior is turned on or off depending  on  the
       value  of  the  XkbRepeatKeysMask  bit, but you must use other means, as described in this
       chapter, to configure its behavior in detail.

RETURN VALUES
       True	      The X server supports a compatible version of Xkb.

       False	      The X server does not support a compatible version of Xkb or the Xkb exten-
		      sion has not been properly initialized.

STRUCTURES
       The XkbControlsRec structure is defined as follows:

	   #define XkbMaxLegalKeyCode	  255
	   #define XkbPerKeyBitArraySize  ((XkbMaxLegalKeyCode+1)/8)

	   typedef struct {
	       unsigned char   mk_dflt_btn;	 /* default button for keyboard driven mouse */
	       unsigned char   num_groups;	 /* number of keyboard groups */
	       unsigned char   groups_wrap;	 /* how to wrap out-of-bounds groups */
	       XkbModsRec      internal;	 /* defines server internal modifiers */
	       XkbModsRec      ignore_lock;	 /* modifiers to ignore when checking for grab */
	       unsigned int    enabled_ctrls;	 /* 1 bit => corresponding boolean control enabled */
	       unsigned short  repeat_delay;	 /* ms delay until first repeat */
	       unsigned short  repeat_interval;  /* ms delay between repeats */
	       unsigned short  slow_keys_delay;  /* ms minimum time key must be down to be ok */
	       unsigned short  debounce_delay;	 /* ms delay before key reactivated */
	       unsigned short  mk_delay;	 /* ms delay to second mouse motion event */
	       unsigned short  mk_interval;	 /* ms delay between repeat mouse events */
	       unsigned short  mk_time_to_max;	 /* # intervals until constant mouse move */
	       unsigned short  mk_max_speed;	 /* multiplier for maximum mouse speed */
	       short	       mk_curve;	 /* determines mouse move curve type */
	       unsigned short  ax_options;	 /* 1 bit => Access X option enabled */
	       unsigned short  ax_timeout;	 /* seconds until Access X disabled */
	       unsigned short  axt_opts_mask;	 /* 1 bit => options to reset on Access X timeout */
	       unsigned short  axt_opts_values;  /* 1 bit => turn option on, 0=> off */
	       unsigned int    axt_ctrls_mask;	 /* which bits in enabled_ctrls to modify */
	       unsigned int    axt_ctrls_values; /* values for new bits in enabled_ctrls */
	       unsigned char   per_key_repeat[XkbPerKeyBitArraySize];  /* per key auto repeat */
	    } XkbControlsRec, *XkbControlsPtr;
