Int 21 Fn 4300  - Dos 2+ - Get File Attributes                             [D]

   AX = 4300h
   DS:DX -> ASCIZ filename

Return: CF clear if successful
       CX = file attributes (see #1107)
       AX = CX (DR DOS 5.0)
   CF set on error
       AX = error code (01h,02h,03h,05h) (see #1366 at AH=59h)

Notes: under the FlashTek X-32 DOS extender, the filename pointer is in DS:EDX
   under DR DOS 3.41 and 5.0, attempts to change the subdirectory bit are
     simply ignored without an error
BUG:   Windows for Workgroups returns error code 05h (access denied) instead
     of error code 02h (file not found) when attempting to get the
     attributes of a nonexistent file.  This causes open() with O_CREAT
     and fopen() with the "w" mode to fail in Borland C++.
