The situation appears to be this: 1. Soft links are available on NTFS 5 (2K/XP) as Reparse Points via the DeviceIoControl() function for any application using the standard C library routines. 2. Soft links are available on any filesystem under 95/98/ME/NT4/2K/XP as OLE streams (.lnk files) for Shell-aware applications. 3. Hard links are available on NTFS 5 (2K/XP) via the CreateHardLink() API. See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/createhardlink.asp 4. Hard links are available on NTFS (NT3.1/NT4) via the BackupWrite() API by writing a special stream to the NTFS. Example: http://www.mvps.org/win32/ntfs/lnw.cpp The cygwin implementation of link(): http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/syscalls.cc?rev=1.149.2.23&content-type=text/x-cvsweb-markup&cvsroot=src 1. Will use CreateHardLink() if on 2K/XP 2. Will try to use the BackupWrite() method 3. Failing #2 will just copy the file See how fun Microsoft makes things?
