2164--DX0005

Category: other operating systems
Flags: Undocumented function

INT 21 - OS/2 v2.1+ Virtual DOS Machine - GET SECOND SFT FLAGS WORD

	AH = 64h
	DX = 0005h (function number)
	CX = 636Ch (magic value, "cl")
	BX = 0000h (indicates special request)
	DI = DOS file handle
Return: AX = value of second flags word from OS/2 SFT entry for file
Notes:	if CX is not 636Ch on entry, INT 21/AH=6Ch is invoked, because a bug
	  in OS/2 1.x FAPI erroneously called AH=64h instead of AH=6Ch
	the OS/2 SFT has two flags words rather than DOS's one word, and this
	  function provides access to the word which is not present in DOS
