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;
