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
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:
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;
