626 * This now (4.0) gets called from two locations:
627 *
628 * -- VirtualBox::init(), to load the global media registry from VirtualBox.xml;

630 * -- Machine::loadMachineDataFromSettings(), to load the per-machine registry
631 * from machine XML, for machines created with VirtualBox 4.0 or later.
632 *
633 * In both cases, the media found are added to the global lists so the
634 * global arrays of media (including the GUI's virtual media manager)
635 * continue to work as before.
636 *
637 * @param uuidMachineRegistry The UUID of the media registry. This is either the
638 * transient UUID created at VirtualBox startup for the global registry or
639 * a machine ID.
640 * @param mediaRegistry The XML settings structure to load, either from VirtualBox.xml
641 * or a machine XML.

2567 * and opened instance to communicate to the Helper process and the given
2568 * Progress object.
2569 *
2570 * The user function is supposed to communicate to the helper process

2573 * call notifyComplete() on it: this will be done automatically using the
2574 * result code returned by the function.
2575 *
2576 * Before the user function is started, the communication channel passed to

2578 * its write() and read() methods directly.

2583 * message using this value will be reported to the caller. Note that the
2584 * value of \a aVrc is inspected only if the user function itself returns
2585 * success.

2587 * If a failure happens anywhere before the user function would be normally
2588 * called, it will be called anyway in special "cleanup only" mode indicated
2589 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
2590 * all the function is supposed to do is to cleanup its aUser argument if
2591 * necessary (it's assumed that the ownership of this argument is passed to
2592 * the user function once #startSVCHelperClient() returns a success, thus
2593 * making it responsible for the cleanup).
