; Copyright (c) 1987-1991, Microsoft Corporation. All rights reserved.
;
;Purpose:
; This file contains the MS-DOS definitions (DOS function request
; numbers, flags, etc) used by the C runtime.
;
;Revision History:
; 10-22-87 JCR Removed "PROTMODE_ONLY" comments
; 02-19-88 SKS STACKSLOP is 256 for DOS, 512 for OS/2
; 06-02-89 JCR Added 386 OS/2 allocmem/setmem flag definitions
; 06-07-89 JCR Bumped STACKSLOP to 1024 for 386 OS/2
; 10-18-89 JCR Changed _NEWREGION to match change in OS2 mem APIs
; 11-02-89 JCR Added DOS32QUERYSYSINFO offset definitions
; 11-10-89 JCR Added OBJ_TILE bit to _NEWREGION memory request
; 06-06-90 SBM Added DOSOPEN flags, names match doscalls.h, added
; tentative new DOS32QUERYFHSTATE flags
; 12-10-90 GJF Updated values of new flags introduced above.
