NAME
       XkbSetBounceKeysDelay - Sets the BounceKeys delay for a keyboard device

SYNOPSIS
       Bool XkbSetBounceKeysDelay ( display, device_spec, delay )

	     Display *display;
	     unsigned int device_spec;
	     unsigned int *delay;

ARGUMENTS
       - display
	      connection to X server

       - device_spec
	      device ID, or XkbUseCoreKbd

       - delay
	      backfilled with bounce keys delay, ms

DESCRIPTION
       The server can generate XkbAccessXNotify events for some of the	global
       keyboard  controls.  The detail field describes what AccessX event just
       occurred and can be any of the values in Table 1.


		       Table 1 AccessXNotify Events

       -------------------------------------------------------------
       detail		   Reason
       -------------------------------------------------------------
       XkbAXN_SKPress	   A key  was  pressed	when  SlowKeys	was

			   enabled.
       XkbAXN_SKAccept	   A key was accepted (held longer than the

			   SlowKeys delay).
       XkbAXN_SKRelease    An accepted SlowKeys key was released.
       XkbAXN_SKReject	   A key was rejected (released before	the

			   SlowKeys delay expired).
       XkbAXN_BKAccept	   A key was accepted by BounceKeys.
       XkbAXN_BKReject	   A  key  was rejected (pressed before the

			   BounceKeys delay expired).
       XkbAXN_AXKWarning   AccessXKeys	is  about  to  turn  on/off

			   StickyKeys or BounceKeys.

       The  keycode  field  reports the keycode of the key for which the event
       occurred. If the action is related to SlowKeys, the slowKeysDelay field
       contains  the  current  SlowKeys  acceptance  delay.  If  the action is
       related to BounceKeys, the debounceDelay  field	contains  the  current
       BounceKeys debounce delay.

       Selecting for AccessX Events

       To  receive  XkbAccessXNotify events under all possible conditions, use
       XkbSelectEvents and pass XkbAccesXNotifyMask in both bits_to_change and
       values_for_bits.

       To  receive  XkbStateNotify  events  only under certain conditions, use
       XkbSelectEventDetails using  XkbAccessXNotify  as  the  event_type  and
       specifying  the	desired  state	changes  in  bits_to_change  and  val-
       ues_for_bits using mask bits from Table 2.

       Some users may accidentally "bounce" on a key  when  they  release  it.
       They press it once, then accidentally press it again after they release
       it. The BounceKeys control temporarily disables a key after it has been
       pressed,  effectively "debouncing" the keyboard. The period of time the
       key is disabled after it is released is known as the BounceKeys	delay.
       BounceKeys is a boolean control.

       When the BounceKeys control is active, the server reports acceptance or
       rejection of any key to interested clients by  sending  an  appropriate
       AccessXNotify event.

       XkbSetBounceKeysDelay  sends a request to configure the BounceKeys con-
       trol to the server. It does not wait for a reply and  normally  returns
       True. Specifying a value of zero for the delay parameter causes XkbSet-
       BounceKeysDelay to generate a BadValue protocol error. If a  compatible
       version	of  the  Xkb extension is not available in the server, XkbSet-
       BounceKeysDelay returns False.

RETURN VALUES
       True	      The XkbSetBounceKeysDelay function returns True when  it
		      sends  a	request to configure the BounceKeys control to
		      the server.

       False	      The XkbSetBounceKeysDelay function returns  False  if  a
		      compatible version of the Xkb extension is not available
		      in the server.

STRUCTURES
       The structure for the XkbAccessXNotify event type is as follows:

       typedef struct {

	   int		  type; 	  /* Xkb extension base event code */
	   unsigned long  serial;	  /* X server serial number for event */
	   Bool 	  send_event;	  /* True => synthetically generated */
	   Display *	  display;	  /* server connection where event generated */
	   Time 	  time; 	  /* server time when event generated */
	   int		  xkb_type;	  /* XkbAccessXNotify */
	   int		  device;	  /* Xkb device ID, will not be XkbUseCoreKbd
       */

	   int		  detail;	  /* XkbAXN_* */
	   KeyCode	  keycode;	  /* key of event */
	   int		  slowKeysDelay;  /* current SlowKeys delay */
	   int		  debounceDelay;  /* current debounce delay */
       } XkbAccessXNotifyEvent;
