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