//  Function:   HrCopyFileAsStream
//
//  Purpose:    Copies a default data stream file as a named stream file
//
//  Arguments:  Same as CopyFile
//
//  Returns:    Same as CopyFile
//
//  Author:     roelfc   30 January 2002
//
//  Notes:      This function replaces the normal CopyFile API by manually 
//              reading the default data stream and writing it as a named 
//              stream to the new file name.
//              This is because applications like eTrust can cause the normal 
//              CopyFile API to fail, since eTrust injects an additional stream 
//              into the file when the incremental scan option is used.
//              (See RAID# 493890: 
//               SFM: File Services for Mac doesn't install with etrust installed.)
