2495 * - executes the supplied function by passing it the created SVCHlpClient
2496 * and opened instance to communicate to the Helper process and the given
2497 * Progress object.
2498 *
2499 * The user function is supposed to communicate to the helper process
2500 * using the \a aClient argument to do the requested job and optionally expose
2501 * the progress through the \a aProgress object. The user function should never
2502 * call notifyComplete() on it: this will be done automatically using the
2503 * result code returned by the function.
2504 *
2505 * Before the user function is started, the communication channel passed to
2506 * the \a aClient argument is fully set up, the function should start using
2507 * its write() and read() methods directly.
2508 *
2509 * The \a aVrc parameter of the user function may be used to return an error
2510 * code if it is related to communication errors (for example, returned by
2511 * the SVCHlpClient members when they fail). In this case, the correct error
2512 * message using this value will be reported to the caller. Note that the
2513 * value of \a aVrc is inspected only if the user function itself returns
2514 * success.
2515 *
2516 * If a failure happens anywhere before the user function would be normally
2517 * called, it will be called anyway in special "cleanup only" mode indicated
2518 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
2519 * all the function is supposed to do is to cleanup its aUser argument if
2520 * necessary (it's assumed that the ownership of this argument is passed to
2521 * the user function once #startSVCHelperClient() returns a success, thus
2522 * making it responsible for the cleanup).
2523 *
2524 * After the user function returns, the thread will send the SVCHlpMsg::Null
2525 * message to indicate a process termination.
2526 *
