/***
*errno.h - system wide error numbers (set by system calls)
*
* Copyright (c) 1985-1993, 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]
*
*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.
* 04-08-93 CFW Added EILSEQ 42.
