▀ The returned path name does not include the drive identifier or a lead-
  ing backslash (). It is terminated with a null (00H) byte. Consequently,
  if the current directory is the root directory, the first byte in the
  buffer will contain 00H.
 
▀ The function fails if the drive code is invalid.
 
▀ The current directory may be set with Int 21H Function 3BH.
