  25 /*  FUNCTION
  26         This function will return the contents of the "currentBinding"
  27         structure. The currentBinding structure may be set with
  28         SetConfigBinding(). This is how arguments are passed to a newly
  29         configured device.
  30
  31         A CurrentBinding structure has the following information:
  32         -   the name of the currently loaded driver file
  33         -   the product string associated with this driver
  34         -   a singly linked list of ConfigDev structures
  35
  36         You may not need this information, but it is recommended that you
  37         at least make sure you can deal with the product code in the
  38         ConfigDev structure.
  39
  40     INPUTS
  41         currentBinding  -   a pointer to the CurrentBinding structure that
  42                             you wish filled in.
  43         bindingSize     -   the size of the currentBinding structure. Do
  44                             not pass less than sizeof(struct CurrentBinding).
  45
  46     RESULT
  47         The size of the CurrentBinding structure returned.
