2632 * and opened instance to communicate to the Helper process and the given
2633 * Progress object.
2634 *
2635 * The user function is supposed to communicate to the helper process
2636 * using the \a aClient argument to do the requested job and optionally expose
2637 * the progress through the \a aProgress object. The user function should never
2638 * call notifyComplete() on it: this will be done automatically using the
2639 * result code returned by the function.
2640 *
2641 * Before the user function is started, the communication channel passed to
2642 * the \a aClient argument is fully set up, the function should start using
2643 * its write() and read() methods directly.
2644 *
2645 * The \a aVrc parameter of the user function may be used to return an error
2646 * code if it is related to communication errors (for example, returned by
2647 * the SVCHlpClient members when they fail). In this case, the correct error
2648 * message using this value will be reported to the caller. Note that the
2649 * value of \a aVrc is inspected only if the user function itself returns
2650 * success.
2651 *
2652 * If a failure happens anywhere before the user function would be normally
2653 * called, it will be called anyway in special "cleanup only" mode indicated
2654 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
2655 * all the function is supposed to do is to cleanup its aUser argument if
2656 * necessary (it's assumed that the ownership of this argument is passed to
2657 * the user function once #startSVCHelperClient() returns a success, thus
2658 * making it responsible for the cleanup).
2659 *
2660 * After the user function returns, the thread will send the SVCHlpMsg::Null
2661 * message to indicate a process termination.
