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;
