*stdio.h - definitions/declarations for standard I/O routines
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file defines the structures, values, macros, and functions
* used by the level 2 I/O ("standard I/O") routines.
* [ANSI/System V]
*
*Revision History:
* 06-24-87 JMB Added char cast to putc macro
* 07-20-87 SKS Fixed declaration of _flsbuf
* 08-10-87 JCR Modified P_tmpdir/L_tmpdir
* 08-17-87 PHG Fixed prototype for puts to take const char * per ANSI.
* 10-02-87 JCR Changed NULL from #else to #elif (C || L || H)
* 10/20/87 JCR Removed "MSC40_ONLY" entries
* 11/09/87 JCR Multi-thread support
* 12-11-87 JCR Added "_loadds" functionality
* 12-17-87 JCR Added _MTHREAD_ONLY comments
* 12-18-87 JCR Added _FAR_ to declarations
* 01-07-88 JCR _NFILE = 40 for mthread includes
* 01-13-88 JCR Removed mthread _fileno_lk/_feof_lk/_ferror_lk declarations
* 01-15-88 JCR DLL versions of stdin/stdout/stderr
* 01-18-88 SKS Change _stdio() to __iob()
* 01-20-88 SKS Change __iob() to _stdin(), _stdout(), _stderr()
* 02-10-88 JCR Cleaned up white space
* 04-21-88 WAJ Added _FAR_ to tempnam/_tmpnam_lk
* 05-31-88 SKS Add FILENAME_MAX and FOPEN_MAX
* 06-01-88 JCR Removed clearerr_lk macro
* 07-28-88 GJF Added casts to fileno() so the file handle is zero
* extended instead of sign extended
* 08-18-88 GJF Revised to also work with the 386 (in small model only).
* 11-14-88 GJF Added _fsopen()
* 12-07-88 JCR DLL _iob[] references are now direct
* 03-27-89 GJF Brought into sync with CRT\H\STDIO.H
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 07-24-89 GJF Changed FILE and fpos_t to be type names rather than
* macros (ANSI requirement). Same as 04-06-89 change in
* CRT
* 07-25-89 GJF Cleanup. Alignment of struct fields is now protected
* by pack pragmas. Now specific to 386.
* 10-30-89 GJF Fixed copyright, removed dummy args from prototypes
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 11-17-89 GJF Added const to appropriate arg type for fdopen() and
* _popen().
* 02-16-90 GJF _iob[], _iob2[] merge
* 03-02-90 GJF Added #ifndef _INC_STDIO and #include <cruntime.h>
* stuff. Also, removed some (now) useless preprocessor
* directives and pragmas.
* 03-21-90 GJF Replaced _cdecl with _CALLTYPE1 or _CALLTYPE2 in
* prototypes.
* 04-10-90 GJF Made _iob[] _VARTYPE1.
* 10-30-90 GJF Moved actual type for va_list into cruntime.h
* 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.
* 08-01-91 GJF No _popen(), _pclose() for Dosx32.
* 08-20-91 JCR C++ and ANSI naming
* 09-24-91 JCR Added _snprintf, _vsnprintf
* 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now
* 01-22-92 GJF Changed definition of _iob for users of crtdll.dll.
* 02-14-92 GJF Replaced _NFILE by _NSTREAM_ for Win32. _NFILE is
* still supported for now, for backwards compatibility.
* 03-17-92 GJF Replaced __tmpnum field in _iobuf structure with
* _tmpfname, altered L_tmpnam definition for Win32.
* 03-30-92 DJM POSIX support.
* 06-02-92 KRS Added Unicode printf versions.
* 08-05-92 GJF Fun. calling type and var. type macro.
* 08-20-92 GJF Some small changes for POSIX.
* 08-20-92 GJF Some small changes for POSIX.
* 09-04-92 GJF Merged changes from 8-5-92 on.
* 11-05-92 GJF Replaced #ifndef __STDC__ with #if !__STDC__. Also,
* undid my ill-advised change to _P_tmpdir.
* 12-12-92 SRW Add L_cuserid constant for _POSIX_
* 01-03-93 SRW Fold in ALPHA changes
* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI
* Use _MIPS_ and _ALPHA_ instead.
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 01-25-93 GJF Cosmetic change to va_list definition.
* 02-01-93 GJF Made FILENAME_MAX 260.
* 03-18-93 CFW Changed BUFSIZ from 512 to 4096
* 03-22-93 CFW Changed BUFSIZ from 4096 to 512 (binaries frozen).
* 04-29-93 CFW Add wide char get/put support.
* 04-30-93 CFW Fixed wide char get/put support.
* 05-04-93 CFW Remove uneeded _filwbuf, _flswbuf protos.
* 06-02-93 CFW Wide get/put use wint_t.
* 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for _M_?????? defines
