Extendiendo la clase File

Hola a todos.
De forma análoga al tema titulado Extendiendo la clase String aprovechare para compartir con ustedes algunas funciones que he ido haciendo y que a mi me resultaron útiles. He aquí la primera de ellas:

Código:
Library "libc:6"

Public Struct stat_

  st_dev As Long

  st_ino As Long

  st_nlink As Long

  st_mode As Integer

  st_uid As Integer

  st_gid As Integer

  __pad0 As Integer

  st_rdev As Long

  st_size As Long

  st_blksize As Long

  st_blocks As Long

  st_atime As Long

  st_atimensec As Long

  st_mtime As Long

  st_mtimensec As Long

  st_ctime As Long

  st_ctimensec As Long

  __glibc_reserved[3] As Long

End Struct

Private Const _STAT_VER_LINUX As Integer = 1

Private Extern __xstat(_STAT_VER As Integer, __path As String, __statbuf As Stat_) As Integer

'' <b>RAD Extension.</b><br>

'' Create a file parameters list using the GNU coreutils program stat. Note: the tags for access to the information are:<br>

'' Dev, Ino, Path, Link, Mode, SetUID, SetGID, Rdev, Size, BlkSize, Blocks, LastAccess, LastModified, LastChange<br>

'' Original <https://www.gambas-it.org/wiki/index.php?title=Stat_()>

Static Public Sub Stat(f As String) As Collection

  Dim i As Integer

  Dim st As New Stat_

  Dim inf As New Collection

  i = __xstat(_STAT_VER_LINUX, f, st)

  If i < 0 Then Error.Raise("Function error '__xstat()' !")

  With st

    inf.Add(.st_dev, "Dev")

    inf.Add(.st_ino, "Ino")

    inf.Add(f, "Path")

    inf.Add(.st_nlink, "Link")

    inf.Add(.st_mode, "Mode")

    inf.Add(.st_uid, "SetUID")

    inf.Add(.st_gid, "SetGID")

    inf.Add(.st_rdev, "Rdev")

    inf.Add(.st_size, "Size")

    inf.Add(.st_blksize, "BlkSize")

    inf.Add(.st_blocks, "Blocks")

    inf.Add(.st_atime, "LastAccess")

    inf.Add(.st_mtime, "LastModified")

    inf.Add(.st_ctime, "LastChange")

  End With

  Return inf

End

Nota: Esta función no hubiese sido posible sin el articulo que Vuott publico en la wiki el foro italiano.
Saludos.
