+*io.h - declarations for low-level file handling and I/O functions
+*
+*	Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	This file contains the function declarations for the low-level
+*	file handling and I/O functions.
+*
+*Revision History:
+*	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
+*	02-10-88  JCR	Cleaned up white space
+*	08-19-88  GJF	Modified to also work for the 386 (small model only)
+*	05-03-89  JCR	Added _INTERNAL_IFSTRIP for relinc usage
+*	08-03-89  GJF	Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
+*	08-14-89  GJF	Added prototype for _pipe()
+*	10-30-89  GJF	Fixed copyright
+*	11-02-89  JCR	Changed "DLL" to "_DLL"
+*	11-17-89  GJF	read() should take "void *" not "char *", write()
+*			should take "const void *" not "char *". Also,
+*			added const to appropriate arg types for access(),
+*			chmod(), creat(), open() and sopen()
+*	03-01-90  GJF	Added #ifndef _INC_IO and #include <cruntime.h>
+*			stuff. Also, removed some (now) useless preprocessor
+*			directives.
+*	03-21-90  GJF	Replaced _cdecl with _CALLTYPE1 or _CALLTYPE2 in
+*			prototypes.
+*	05-28-90  SBM	Added _commit()
+*	01-18-91  GJF	ANSI naming.
+*	02-25-91  SRW	Exposed _get_osfhandle and _open_osfhandle [_WIN32_]
+*	08-01-91  GJF	No _pipe for Dosx32.
+*	08-20-91  JCR	C++ and ANSI naming
+*       08-26-91  BWM   Added _findfirst, etc.
+*       09-16-91  BWM   Changed find handle type to long.
+*	09-28-91  JCR	ANSI names: DOSX32=prototypes, WIN32=#defines for now
+*	03-30-92  DJM	POSIX support.
+*	06-23-92  GJF	// is non-ANSI comment delimiter.
+*	08-06-92  GJF	Function calling type and variable type macros.
+*	08-25-92  GJF	For POSIX build, #ifdef-ed out all but some internally
+*			used macros (and these are stripped out on release).
+*	09-03-92  GJF	Merge two changes above.
+*	01-21-93  GJF	Removed support for C6-386's _cdecl.
+*	05-11-93  SKS	Increased name buffer in finddata structure to 260 bytes.
