  _In_opt_ const void**                    arguments,
  _In_     WS_HEAP*                        heap,
           const WS_CALL_PROPERTY*         callProperties,
  _In_     const ULONG                     callPropertyCount,
  _In_opt_ const WS_ASYNC_CONTEXT*         asyncContext,
  _In_opt_ WS_ERROR*                       error
);

Parameters

serviceProxy [in]

Pointer to a WS_SERVICE_PROXY structure representing the service proxy.

operation [in]
