PARAMETERS
  The parameter definitions are the same for the API and the SPI.

  ModuleHandle (input)            The handle of the attached
                                  HRS service provider.
  GuiStreamingCallback (input)    A pointer to an application
                                  callback to deal with the
                                  presentation of biometric
                                  streaming data.
  GuiStreamingCallbackCtx (input) A generic pointer to context
                                  information provided by the
                                  application that will be presented
                                  on the callback.
  GuiStateCallback (input)        A pointer to an application
                                  callback to deal with GUI state
                                  changes.
  GuiStateCallbackCtx (input)     A generic pointer to context
                                  information provided by the application
                                  that will be presented on the callback.

DESCRIPTION
  This function allows the application to establish callbacks so that
  the application may control the "look-and-feel" of the biometric user
  interface.  Note that not all HRS service providers provide streaming
  data.

RETURN VALUE
  A CSSM_RETURN value indicating success or specifying a particular
  error condition. The value CSSM_OK indicates success. All other
  values represent an error condition.

ERRORS
  Errors are described in the CDSA Technical Standard.  See CDSA.

  CSSMERR_CSSM_NOT_INITIALIZED
  CSSMERR_CSSM_FUNCTION_FAILED
  CSSMERR_CSSM_FUNCTION_NOT_IMPLEMENTED
  CSSMERR_CSSM_FUNCTION_INTEGRITY_FAIL
