|
*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
|
||
|
|
