52/** UUID memory representation. Array of 16 bytes.
53 *
54 * @note VirtualBox uses a consistent binary representation of UUIDs on all platforms. For this reason
55 * the integer fields comprising the UUID are stored as little endian values. If you want to pass such
56 * UUIDs to code which assumes that the integer fields are big endian (often also called network byte
57 * order), you need to adjust the contents of the UUID to e.g. achieve the same string representation.
58 *
59 * The required changes are:
60 * - reverse the order of byte 0, 1, 2 and 3
61 * - reverse the order of byte 4 and 5
62 * - reverse the order of byte 6 and 7.
63 *
64 * Using this conversion you will get identical results when converting the binary UUID to the string
65 * representation.
