*_file.c - perprocess file and buffer data declarations
*
* Copyright (c) 1985-1992, Microsoft Corporation. All rights reserved.
*
*Purpose:
* file and buffer data declarations
*
*Revision History:
* 04-18-84 RN initial version
* ??-??-?? TC added field _bifsiz to iob2 to allow variable
* length buffers
* 10-02-86 SKS _NFILE_ is now different for real-mode and prot-mode
* _NFILE_ must be defined by compiler -D directory
* 05-27-87 JCR Protected mode now uses only 3 pre-defined file handles,
* not 5. Added PM (prot mode) to conditionalize handles.
* 06-24-87 SKS Make "_bufin[]" and "_bufout[]" near for Compact/Large
* models (MS real-mode version only)
* 07-01-87 PHG Changed PM switch to PROTMODE
* 11-05-87 JCR Added _buferr and modified stderr entry
* 11-09-87 SKS Removed IBMC20 switch, Changed PROTMODE to OS2
* 01-04-88 JCR Moved _NFILE_ definition from command line to file
* 01-11-88 JCR Merged Mthread version into standard version
* 01-21-88 JCR Removed reference to internal.h and added _NEAR_
* (thus, internal.h doesn't get released in startup
* sources even though _file.c does).
* 06-28-88 JCR Remove static stdout/stderr buffers
* 07-06-88 JCR Corrected _bufin declaration so it's always in BSS
* 08-24-88 GJF Added check that OS2 is defined whenever M_I386 is.
* 06-08-89 GJF Propagated SKS's fix of 02-08-89, and fixed copyright.
* 07-25-89 GJF Cleanup (deleted DOS specific and OS/2 286 specific
* stuff). Now specific to the 386.
* 01-09-90 GJF _iob[], _iob2[] merge. Also, fixed copyright
* 03-16-90 GJF Added #include <cruntime.h> and removed some (now)
* useless preprocessor stuff.
* 03-26-90 GJF Replaced _cdecl with _VARTYPE1.
* 02-14-92 GJF Replaced _NFILE_ with _NSTREAM_ for Win32, with _NFILE
* for non-Win32.
