XkbNoteDeviceChanges(3) XKB FUNCTIONS XkbNoteDeviceChanges(3)
NAME
XkbNoteDeviceChanges - Note device changes reported in an XkbExtensionDeviceNotify event
SYNOPSIS
void XkbNoteDeviceChanges ( old, new, wanted )
XkbDeviceChangesPtr old;
XkbExtensionDeviceNotifyEvent * new;
unsigned int wanted;
ARGUMENTS
- old structure tracking state changes
- new event indicating state changes
- wanted
mask indicating changes to note
DESCRIPTION
The wanted field specifies the changes that should be noted in old, and is composed of the bitwise
inclusive OR of one or more of the masks from Table 1. The reason field of the event in new indicates
the types of changes the event is reporting. XkbNoteDeviceChanges updates the XkbDeviceChangesRec
specified by old with the changes that are both specified in wanted and contained in new->reason.

To update a local copy of the state and configuration of an X input extension device with the changes
previously noted in an XkbDeviceChangesRec structure, use XkbGetDeviceInfoChanges.
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;
