.SH NAME
XkbChangeDeviceInfo \- Update the server's description of a device with the changes noted in an
XkbDeviceChangesRec
.SH SYNOPSIS
.HP
.B Bool XkbChangeDeviceInfo
.BI "(\^Display *" "dpy" "\^,"
.BI "XkbDeviceInfoPtr " "device_info" "\^,"
.BI "XkbDeviceChangesPtr " "changes" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- dpy
connection to X server
.TP
.I \- device_info
local copy of device state and configuration
.TP
.I \- changes
note specifying changes in 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;
.fi
