*fcntl.h - file control options used by open()
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file defines constants for the file control options used
* by the _open() function.
* [System V]
*
*Revision History:
* 06-19-87 JCR Added O_NOINHERIT
* 08-18-88 GJF Modified (slightly) to also work for the 386.
* 08-01-89 GJF Fixed copyright
* 10-30-89 GJF Fixed copyright
* 02-28-90 GJF Added #ifndef _INC_FCNTL stuff. Made the definition
* of O_BINARY a 32-bit constant unconditionally.
* 01-17-91 GJF ANSI naming.
* 03-30-92 DJM POSIX support.
* 05-02-92 SRW Add support for _O_TEMPORARY flag
* 05-24-93 PML Add support for _O_SHORT_LIVED, _O_SEQUENTIAL,
* _O_RANDOM
