** Module Name:
**
**	simsnap.cpp
**
**
** Abstract:
**
**	Test program to drive the VSS Writer Shim contained in VssAPI.DLL
**
**
** Author:
**
**	Michael C. Johnson   [mikejohn]        24-May-2000
**
**
** Revision History:
**
**	X-5	MCJ		Michael C. Johnson		15-Sep-2000
**		Add test for invalid volume array pointer, interleaved calls
**		and so on.
**
**	X-4	MCJ		Michael C. Johnson		15-Sep-2000
**		Add test for invalid bits in options parameter of call to
**		SimulateSnapshotFreeze()
**
**	X-3	MCJ		Michael C. Johnson		30-Jun-2000
**		Remove calls to RegisterSnapshotSubscriptions() and 
**		UnregisterSnapshotSubscriptions() as these are no longer 
**		required.
**
**	X-2	MCJ		Michael C. Johnson		26-May-2000
**		Add some extra tests to validate shim is properly sensitive
**		to volume name array contents.
