-
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;
