2023 * - executes the supplied function by passing it the created SVCHlpClient
2024 * and opened instance to communicate to the Helper process and the given
2025 * Progress object.
2026 *
2027 * The user function is supposed to communicate to the helper process
2028 * using the \a aClient argument to do the requested job and optionally expose
2029 * the progress through the \a aProgress object. The user function should never
2030 * call notifyComplete() on it: this will be done automatically using the
2031 * result code returned by the function.
2032 *
2033 * Before the user function is started, the communication channel passed to
2034 * the \a aClient argument is fully set up, the function should start using
2035 * its write() and read() methods directly.
2036 *
2037 * The \a aVrc parameter of the user function may be used to return an error
2038 * code if it is related to communication errors (for example, returned by
2039 * the SVCHlpClient members when they fail). In this case, the correct error
2040 * message using this value will be reported to the caller. Note that the
2041 * value of \a aVrc is inspected only if the user function itself returns
2042 * success.
2043 *
2044 * If a failure happens anywhere before the user function would be normally
2045 * called, it will be called anyway in special "cleanup only" mode indicated
2046 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
2047 * all the function is supposed to do is to cleanup its aUser argument if
2048 * necessary (it's assumed that the ownership of this argument is passed to
2049 * the user function once #startSVCHelperClient() returns a success, thus
2050 * making it responsible for the cleanup).
