Deleting hard links problem
time to read 2 min | 214 words
This code fails:
[DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] public static extern bool CreateHardLink(string lpFileName, string lpExistingFileName, IntPtr lpSecurityAttributes); static void Main() { var writer = File.CreateText("test.txt"); writer.Write("test"); writer.Flush(); CreateHardLink("hard_link.txt", "test.txt", IntPtr.Zero); File.Delete("hard_link.txt"); }
The problem here is that the hard_link.txt file is considered to be open. What I would expect to happen is that the delete would succeed in removing the directory entry, but keep the file. In other words, I would only expect it to fail if this is the last directory entry for the file (resulting in an actual delete).
For now I changed this to try to delete, but on failure, mark the file to be deletes on the next reboot.
