If I compile small (like empty) win32 c++ WinMain app to exe and disasembly it i see
some stubs of code there, containing such functions (i will post it as it my be helpfull and i would like to understand it most fully as possible)

I found thet probably source related to this stub is maybe here
 
http://sourceforge.net/p/mingw/mingw-org-wsl/ci/21762bb4a1bd0c88c38eead03f59e8d994349e83/tree/src/libcrt/crt/
 
(could someone acknowledge that?)
 
But still i cannot track the entry point and full order of operations and see clearly what
is injected and esp the prder of callings,
 
could someone help in understanding that
writing a couple of words of short comment like tutorial explaining what is called where
and so on?
 
tnx

I use a framework that generates mock functions from an interface
description (basically a function prototype described in XML) so the
cost is low compared to the benefits.

What does Ian say on this? ("I mock everything the code under test calls")
My variant is a macro which throws in DEBUG in combination with a class calling in some loops a test function until nothing is thrown and a list of allocated resources.

I was responding to your comment that "I read the header file to see
the API". I do not do so: I look at the documentation to see the API.
 
If your point does not concern libraries (or other similar code intended
to be used by other modules which ought to be documented), then the
interest group for the hypothetical header file containing class
definitions comprises the authors and maintainers of the code. In
order for the maintainer to maintain (and so understand) any given
class method, she needs to look at the data that the class is operating
on.
 
For inline and/or template methods in particular, that in my view is
something best done by declaring the class data before declaring the
public methods. I see zero advantage in declaring the public methods
in advance of the data, as proposed in the style guide.

If others are interested in a C++ meeting in the St. Paul,
Minnesota area, please let me know. By the grace of G-d,
I'm able to provide a meeting area in a conference room in
the office building where Ebenezer Enterprises is, and I
would be happy to give a talk or two.
