|
|
updates the server's description of the device specified in

|
.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;
