can "stdio.h" be OS specific at the kernal level or ? i know what I'm
trying to ask here but not sure how to word it :-)

They are trying to do so more and more, but they
botched many things in the past and are stuck with
them.
Microsoft has both standard features and proprietary features, and the
documentation does not says what is standard and portable and what is
proprietary. For instance, fopen(name, "wb") is not documented as being
Windows-only.
This policy is surely to simplify porting the code to Windows, but not from
Windows :)
As about "MS not following the standards" if we are speaking about languages -
then they have some STL implementation different a bit from the SGI's STL.
People who were porting the heavy-use-STL code from Linux to Windows had
problems due to this. I think that probably MS uses the obsolete STL standard.
Anyway this is C++ and not C.
BTW - when MS had their Java toolkit, they strictly divided "Sun's
documentation" from "MS's documentation". If you used features from Sun's
documentation only - then the Java code was portable and multi-platform.
Nevertheless, among MS-only extensions to Java there were the analogs of
LoadLibrary/GetProcAddress (dlopen() and dlsym() in UNIXen), and MS recommended
them for use to call Windows-only native machine code from Java code. This is
what caused Sun to become outrageous and starting the lawsuit.
For now, they have C# and .NET with a similar feature called "pinvoke". I dunno
what is better - Java or .NET. From what I've heard on people working with
these tools, .NET designers were taught by Java's weak places, and thus C#/.NET
is better then Java - they have removed/reworked some things which were badly
designed in Java.

The C standard defines what has to be in stdio.h.
Or, at least it defines what happens when the compiler encounters:
#include <stdio.h>
You might want to read chapter 7 and specifically 7.19
:-)
I have. What's your point?
Nothing in the standard says that stdio.h actually has to exist, or
that it actually has to be a file on disk, containing C code. You only
know that by typing:
#include <stdio.h>
in C source code, you will get declarations of several functions,
macros and types.

I am glad to hear this -- because it would be wrong.
'w' and 'b' are both standard C, as is "wb".
Do you mean "wt" (instead of standard "w")?
Cheers

I've never said that it did - in fact if you read my comments elsethread you'll
see I said the same thing. I don't see that as remotely relevant tho.
The standard lists what is defined in stdio.h. Whether its "in" as in "inside
some file" or "in" as in "in pixie dust and copied into your translation unit
during phase x of compilation" is highly immaterial.

I think "wb" is standard, but I may be mistaken.

Prior to Visual C++ 7.0, the support for templates was very scarce and
the STL is all about templates, which made the standard library quite
non-compliant. From 7.1, it gets quite close to full compliance.

I saw Linux failing fopen() if "wb" is specified, so I considered this to be
Microsoftism.
It was old ago in 2000 though.
