2970 * Helper method that starts a worker thread that:
2971 * - creates a pipe communication channel using SVCHlpClient;
2972 * - starts an SVC Helper process that will inherit this channel;
2973 * - executes the supplied function by passing it the created SVCHlpClient
2974 * and opened instance to communicate to the Helper process and the given
2975 * Progress object.
2976 *
2977 * The user function is supposed to communicate to the helper process
2978 * using the \a aClient argument to do the requested job and optionally expose
2979 * the progress through the \a aProgress object. The user function should never
2980 * call notifyComplete() on it: this will be done automatically using the
2981 * result code returned by the function.
2982 *
2983 * Before the user function is started, the communication channel passed to
2984 * the \a aClient argument is fully set up, the function should start using
2985 * its write() and read() methods directly.
2986 *
2987 * The \a aVrc parameter of the user function may be used to return an error
2988 * code if it is related to communication errors (for example, returned by
2989 * the SVCHlpClient members when they fail). In this case, the correct error
2990 * message using this value will be reported to the caller. Note that the
2991 * value of \a aVrc is inspected only if the user function itself returns
2992 * success.
2993 *
2994 * If a failure happens anywhere before the user function would be normally
2995 * called, it will be called anyway in special "cleanup only" mode indicated
2996 * by \a aClient, \a aProgress and \a aVrc arguments set to NULL. In this mode,
2997 * all the function is supposed to do is to cleanup its aUser argument if
2998 * necessary (it's assumed that the ownership of this argument is passed to
2999 * the user function once #startSVCHelperClient() returns a success, thus
3000 * making it responsible for the cleanup).
3001 *
3002 * After the user function returns, the thread will send the SVCHlpMsg::Null
3003 * message to indicate a process termination.
3004 *
3005 * @param aPrivileged |true| to start the SVC Helper process as a privileged
3006 * user that can perform administrative tasks
3007 * @param aFunc user function to run
3008 * @param aUser argument to the user function
3009 * @param aProgress progress object that will track operation completion
3010 *

3013 * process.
