XkbGetGeometry - Loads a keyboard geometry if you already have the keyboard description

dpy    connection to the X server

       xkb    keyboard  description  that contains the ID for the keyboard and into which the geometry should be
              loaded

       You can load a keyboard geometry  as  part  of  the  keyboard  description  returned  by  XkbGetKeyboard.
       However,  if  a  keyboard  description has been previously loaded, you can instead obtain the geometry by
       calling the XkbGetGeometry.  In this case, the geometry returned is the one associated with the  keyboard
       whose device ID is contained in the keyboard description.

       XkbGetGeometry  can return BadValue, BadImplementation, BadName, BadAlloc, or BadLength errors or Success
       if it succeeds.

BadAlloc       Unable to allocate storage

       BadImplementation
                      Invalid reply from server

       BadLength      The length of a request is shorter or longer than that required to minimally  contain  the
                      arguments

       BadName        A font or color of the specified name does not exist

       BadValue       An argument is out of range
