Int 21 Fn 5703  - Dos 4.x Only - Get Extended Attribute Properties         [D]

   AX = 5703h
   BX = file handle
   CX = size of result buffer or 0000h
   ES:DI -> result buffer

Return: CF clear if successful
       CX = size of returned data
   CF set on error
       AX = error code (see #1366)
   ES:DI -> zero word (DOS 4.0) if CX >= 2 on entry
Desc:  get a list of the extended attributes which are defined for the
     specified file

Notes: if CX=0000h on entry, ES:DI is ignored and no data is actually
     returned, only the amount of data which is available
   the default DOS 4 behavior is to return a trivial EAP list consisting
     of the single word 0000h (no EAP structures) if CX>=0002h on entry;
     this functionality was apparently never released to the public
