INT 21 - DOS 4.x only - GET EXTENDED ATTRIBUTES FOR FILE

	AX = 5702h
	BX = file handle
	CX = size of result buffer or 0000h
	DS:SI -> EAP list (see #01667)
	ES:DI -> buffer for returned EAV list (see #01670)
Return: CF clear if successful
	    CX = size of returned data
	CF set on error
	    AX = error code (see #01680)
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
