actual = GetCurrentBinding( currentBinding, size )
      
     
  
    This function writes the contents of the "currentBinding" structure out of a private place.  It may be set via 
SetCurrentBinding().  This is really a kludge, but it is the only way to pass extra arguments to a newly configured device.
    A CurrentBinding structure has the name of the currently loaded file, the product string that was associated with this driver, and a pointer to the head of a singly linked list of ConfigDev structures (linked through the cd_NextCD field).
    Many devices may not need this information; they have hard coded into themselves their manufacture number.  It is recommended that you at least check that you can deal with the product code in the linked ConfigDev structures.
