*time.h - definitions/declarations for time routines
|

* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* This file has declarations of time routines and defines
|
|
* the structure returned by the localtime and gmtime routines and
|
|
* used by asctime.
|
|
* [ANSI/System V]
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 07-27-87 SKS Added _strdate(), _strtime()
|
|
* 10-20-87 JCR Removed "MSC40_ONLY" entries
|
|
* 12-11-87 JCR Added "_loadds" functionality
|
|
* 12-18-87 JCR Added _FAR_ to declarations
|
|
* 01-16-88 JCR Added function versions of daylight/timezone/tzset
|
|
* 01-20-88 SKS Change _timezone(n) to _timezone(), _daylight()
|
|
* 02-10-88 JCR Cleaned up white space
|
|
* 12-07-88 JCR DLL timezone/daylight/tzname now directly refers to data
|
|
* 03-14-89 JCR Added strftime() prototype and size_t definition
|
|
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
|
|
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
|
|
* 10-30-89 GJF Fixed copyright, removed dummy args from prototypes
|
|
* 11-02-89 JCR Changed "DLL" to "_DLL"
|
|
* 11-20-89 JCR difftime() always _cdecl (not pascal even under mthread)
|
|
* 03-02-90 GJF Added #ifndef _INC_TIME and #include <cruntime.h>
|
|
* stuff. Also, removed some (now) useless preprocessor
|
|
* directives.
|
|
* 03-29-90 GJF Replaced _cdecl with _CALLTYPE1 in prototypes and with
|
|
* _VARTYPE1 in variable declarations.
|
|
* 08-16-90 SBM Added NULL definition for ANSI compliance
|
|
* 11-12-90 GJF Changed NULL to (void *)0.
|
|
* 01-21-91 GJF ANSI naming.
|
|
* 02-12-91 GJF Only #define NULL if it isn't #define-d.
|
|
* 08-20-91 JCR C++ and ANSI naming
|
|
* 08-26-91 BWM Added prototypes for _getsystime and _setsystem.
|
|
* 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now
|
|
* 01-22-92 GJF Fixed up definitions of global variables for build of,
|
|
* and users of, crtdll.dll.
|
|
* 03-25-92 DJM POSIX support.
|
|
* 08-05-92 GJF Function calling type and variable type macros.
|
|
* 08-24-92 PBS Support for Posix TZ variable.
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
|
|
* 03-10-93 MJB Fixes for Posix TZ stuff.
|
|
* 03-20-93 SKS Remove obsolete functions _getsystime/_setsystime
|
|
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
|
|
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
|
|
* Use link-time aliases for old names, not #define's
|
|
* Remove POSIX #ifdef's
|
|
* 05-05-93 CFW Add wcsftime proto.
|
|
* 06-08-93 SKS Cannot #define the old name "timezone" to "_timezone"
|
|
* because of conflict conflict with the timezone field
|
|
* in struct timeb in <sys/timeb.h>.
|
|
* 09-13-93 GJF Merged NT SDK and Cuda versions.
|
|
* 11-15-93 GJF Enclosed _getlocaltime, _setlocaltime prototypes with
|
|
* a warning noting they are obsolete.
|
|
* 12-07-93 CFW Add wide char version protos.
|
|
* 12-07-93 CFW Move wide defs outside __STDC__ check.
|
|
* 04-13-94 GJF Made _daylight, _timezone and _tzname into deferences
|
|
* of function return values (for compatibility with the
|
|
* Win32s version of msvcrt*.dll). Also, added
|
|
* conditional include for win32s.h.
|
|
* 05-04-94 GJF Made definitions of _daylight, _timezone and _tzname
|
|
* for _DLL conditional on _M_IX86 also.

|
|
* 08-30-95 GJF Added _dstbias.
|
|
* 12-14-95 JWM Add "#pragma once".

|
|
* 05-04-98 GJF Added __time64_t support.
|
|
* 01-06-99 GJF Changes for 64-bit size_t.
|

* 05-13-99 PML Remove _CRTAPI1
|
|
* 05-17-99 PML Remove all Macintosh support.
|
|
* 10-06-99 PML Add _W64 modifier to types which are 32 bits in Win32,
