Int 21 Fn 5702  - Dos 4.x Only - Get Extended Attributes For File          [D]

   AX = 5702h
   BX = file handle
   CX = size of result buffer or 0000h
   DS:SI -> EAP list (see #1353)
   ES:DI -> buffer for returned EAV list (see #1356)

Return: CF clear if successful
       CX = size of returned data
   CF set on error
       AX = error code (see #1366)
Desc:  get the current value of one or more extended attributes

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 single word of 0000h (no
     structures) in the result buffer if CX>=0002h on entry; this
     functionality was apparently never released to the public
