	// Note  The structures that are transmitted within ByteStream are not marshaled in

	// layout and field types are those found on the Windows/Intel 32-bit and 64-bit architectures,
	// and, Windows/AMD 64-bit architecture. These structures are not packed, and padding
	// bytes can exist between successive structure fields to ensure that the field of a
	// given data type begins at a byte offset that is an integer multiple of the type's
	// size with respect to the beginning of the structure. The structures transmitted within
	// ByteStream also appear in other interfaces as RPC-marshaled structures. In these
	// interfaces, the structure fields will be marshaled in NDR format.
	//
	// *
	//
	// The structure is copied one byte at a time from memory into ByteStream beginning
	// at first byte after action field. If the structure contains character pointer fields,
	// those fields are omitted.
	//
	// *
	//
	// The character strings of the character pointer fields are copied into ByteStream
	// following the structure in the order in which they appear in the structure. All strings
	// are null-terminated. There is no padding between the end of the structure and the
	// first string, or between successive strings.
	//
	// At the client, the following technique is used to parse the byte stream back into
	// the appropriate structures:
	//
	// *
	//
	// The notification size, type, and action are parsed from the byte stream.
	//
	// *
	//
	// The notification object structure, up through the first string field, is copied out
	// of the byte stream and into the appropriate structure. For the IVolumeClient interface,
	// the disk ( 3c91641b-e5cd-409e-a445-2e4d61ae33c6#gt_c4133b2a-a990-4042-ba44-7fda3090f118
	// ) and region structures are DISK_INFO and REGION_INFO; for the IVolumeClient3 interface,
	// the structures are DISK_INFO_EX and REGION_INFO_EX. The client's ObjectsChanged implementation
	// MUST switch based on which version of the IVolumeClient interface is being used.
	// The client MUST also determine the type of processor architecture for both the server
	// and client. If the architectures are the same, the padding in the client-defined
	// structures will match that used in the server's byte stream. If the architectures
	// are not the same, the client MUST use the proper method for parsing the byte stream,
	// taking into account padding that MAY have been added for alignment purposes on either
	// the client or on the server. For more information, see section 8 ( 562d58df-633f-4afa-89ec-80917a2852b3
	// ).

	// Allocations are done on the client to hold the character strings of the character
