/***
*errno.h - system wide error numbers (set by system calls)
*
*       Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       This file defines the system-wide error numbers (set by
*       system calls).  Conforms to the XENIX standard.  Extended
*       for compatibility with Uniforum standard.
*       [System V]
*
*       [Public]
*
*Revision History:
*       07-15-88  JCR   Added errno definition [ANSI]
*       08-22-88  GJF   Modified to also work with the 386 (small model only)
*       05-03-89  JCR   Added _INTERNAL_IFSTRIP for relinc usage
*       08-01-89  GJF   Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
*       10-30-89  GJF   Fixed copyright
*       11-02-89  JCR   Changed "DLL" to "_DLL"
*       02-28-90  GJF   Added #ifndef _INC_ERRNO and #include <cruntime.h>
*                       stuff. Also, removed some (now) useless preprocessor
*                       directives.
*       03-29-90  GJF   Replaced _cdecl with _CALLTYPE1 or _VARTYPE1, as
*                       appropriate.
*       08-16-90  SBM   Made MTHREAD _errno() return int *
*       08-20-91  JCR   C++ and ANSI naming
*       08-06-92  GJF   Function calling type and variable type macros.
*       10-01-92  GJF   Made compatible with POSIX. Next step is to renumber
*                       to remove gaps (after next beta).
*       01-21-93  GJF   Removed support for C6-386's _cdecl.
*       04-06-93  SKS   Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
*       04-07-93  SKS   Add _CRTIMP keyword for CRT DLL model
*       04-08-93  CFW   Added EILSEQ 42.
*       09-01-93  GJF   Merged Cuda and NT SDK versions.
*       06-06-94  SKS   Change if def(_MT) to if def(_MT) || def(_DLL)
*                       This will support single-thread apps using MSVCRT*.DLL
*       02-11-95  CFW   Add _CRTBLD to avoid users getting wrong headers.
*       02-14-95  CFW   Clean up Mac merge.
*       12-14-95  JWM   Add "#pragma once".
*       02-20-97  GJF   Cleaned out obsolete support for _CRTAPI* and _NTSDK.
*                       Replaced !defined(_M_MPPC) && !defined(_M_M68K) with
*                       !defined(_MAC). Also, detab-ed.
*       09-30-97  JWM   Restored not-so-obsolete _CRTAPI1 support.
*       10-07-97  RDL   Added IA64.
*       05-13-99  PML   Remove _CRTAPI1
*       05-17-99  PML   Remove all Macintosh support.
