+.I \- device_info

+.SH DESCRIPTION
+.LP
+.I XkbChangeDeviceInfo
+updates the server's description of the device specified in
+.I device_info->device_spec
+with the changes specified in
+.I changes
+and contained in
+.I device_info.
+The update is made by an
+.I XkbSetDeviceInfo
+request.
+.SH STRUCTURES
+.LP
+Changes to an Xkb extension device may be tracked by listening to XkbDeviceExtensionNotify events
+and accumulating the changes in an XkbDeviceChangesRec structure. The changes noted in the
+structure may then be used in subsequent operations to update either a server configuration or a
+local copy of an Xkb extension device configuration. The changes structure is defined as follows:
+.nf
+
+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;
