Name: dos_fs.h
Date Updated: $./FDT$ $./FTM$
Description: This file contains the prototypes for the DOS
file system functions.
$Log: O:/LOGFILES/DOS_FS.H_V $
*
* Rev 1.10 03 Nov 1992 16:29:58 TIMN
* Added macros for processing streams
*
* Rev 1.9 21 Oct 1992 13:09:06 CARLS
* changed DOS_SetHandObjSizeLo to DOS_SetHandObjSize because size is now UINT64
*
* Rev 1.8 29 Sep 1992 17:47:28 CHUCKB
* Added s_info to prototype for DOSCompleteBlk().
*
* Rev 1.7 24 Sep 1992 12:00:48 TIMN
* Deleted references to f(x) FS_GetTotalSizeDBLK()
*
* Rev 1.6 24 Sep 1992 11:58:04 TIMN
* Updated DOS FileSys to support MTF v4.0 format (stream info structs in data streams)
*
* Rev 1.5 14 May 1992 17:03:24 STEVEN
* 40 format
*
* Rev 1.4 13 May 1992 16:50:02 STEVEN
