SYNOPSIS

XkbDeviceChangesPtr changes);

ARGUMENTS

dpy connection to X server

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;
