XkbNoteDeviceChanges(3)		 XKB FUNCTIONS	       XkbNoteDeviceChanges(3)

NAME
       XkbNoteDeviceChanges - Note device changes reported in an XkbExtension‐
       DeviceNotify event

SYNOPSIS
       void XkbNoteDeviceChanges ( old, new, wanted )
	     XkbDeviceChangesPtr old;
	     XkbExtensionDeviceNotifyEvent * new;
	     unsigned int wanted;

ARGUMENTS
       - old  structure tracking state changes

       - new  event indicating state changes

       - wanted
	      mask indicating changes to note

DESCRIPTION
       The wanted field specifies the changes that should be noted in old, and
       is  composed  of	 the  bitwise inclusive OR of one or more of the masks
       from Table 1. The reason field of the event in new indicates the	 types
       of  changes  the	 event is reporting.  XkbNoteDeviceChanges updates the
       XkbDeviceChangesRec specified by old with the  changes  that  are  both
       specified in wanted and contained in new->reason.

       XkbXI_KeyboardsMask			     (1L <<0) Clients can use all
							      Xkb requests and events
							      with KeyClass devices
							      supported by the input
							      device extension.

       XkbXI_ButtonActionsMask	     num_btns	     (1L <<1) Clients can assign key
				     btn_acts		      actions to buttons
							      non-KeyClass input
							      extension devices.

       XkbXI_IndicatorNamesMask	     leds->names     (1L <<2) Clients can assign
							      names to indicators on
							      non-KeyClass input
							      extension devices.

       XkbXI_IndicatorMapsMask	     leds->maps	     (1L <<3) Clients can assign
							      indicator maps to
							      indicators on
							      non-KeyClass input
							      extension devices.

       XkbXI_IndicatorStateMask	     leds->state     (1L <<4) Clients can request
							      the status of indicators
							      on non-KeyClass input
							      extension devices.

       To  update  a  local  copy of the state and configuration of an X input
       extension device	 with  the  changes  previously	 noted	in  an	XkbDe‐
       viceChangesRec structure, use XkbGetDeviceInfoChanges.

STRUCTURES
       Changes	to an Xkb extension device may be tracked by listening to Xkb‐
       DeviceExtensionNotify events and accumulating the changes in an	XkbDe‐
       viceChangesRec  structure.  The changes noted in the structure may then
       be used in subsequent operations to update either a  server  configura‐
       tion  or	 a  local  copy	 of an Xkb extension device configuration. The
       changes structure is defined as follows:

       typedef struct _XkbDeviceChanges {
	   unsigned int		changed;       /∗ bits indicating what has changed */
	   unsigned short	first_btn;     /∗ number of first button which changed, if any */
	   unsigned short	num_btns;      /∗ number of buttons that have changed */
	   XkbDeviceLedChangesRec leds;
       } XkbDeviceChangesRec,*XkbDeviceChangesPtr;
