XkbChangeDeviceInfo(3)						   XKB FUNCTIONS					    XkbChangeDeviceInfo(3)

NAME
       XkbChangeDeviceInfo - Update the server's description of a device with the changes noted in an XkbDeviceChangesRec

SYNOPSIS
       Bool XkbChangeDeviceInfo (Display *dpy, XkbDeviceInfoPtr device_info, XkbDeviceChangesPtr changes);

ARGUMENTS
       - dpy  connection to X server

       - device_info
	      local copy of device state and configuration

       - changes
	      note specifying changes in device_info

DESCRIPTION
       XkbChangeDeviceInfo  updates  the  server's  description  of the device specified in device_info->device_spec with the changes specified in
       changes and contained in device_info.  The update is made by an XkbSetDeviceInfo request.

STRUCTURES
       Changes to an Xkb extension device may be tracked by listening to XkbDeviceExtensionNotify 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;
