//              22-Feb-96      MikeHill Added several new member functions.
//              29-Feb-96      MikeHill Removed include of propmac.hxx
//                                      Moved 2 inlines to propstm.cxx
//              09-May-96      MikeHill Update _InitSection & _FixSummaryInformation
//                                      prototypes.
//              22-May-96      MikeHill Update prototypes for new OSVersion parameter,

//              01-Jul-96      MikeHill - Modified to allow removal of Win32 SEH.
//                                      - Added byte-swapping support.
//              07-Feb-97      Danl     - Changed CMappedStream to IMappedStream.
//
//
// Notes:       This implementation of property streams has no notion of
//              sections in a property set.

//              in kernel mode, and just one implementation for parsing the
//              contents of the stream (CPropertySetStream)
//--------------------------------------------------------------------------
