1. Are linkage convention and calling convention referring to the same
thing?
2. Does calling convention differ between languages C and C++?
3. How does calling convention differ between static and non-static class
member function?
4. Could it be possible to specify different calling convention for each
"global" or each class member function? Even in a single file scope?

I've read calling conventions to be the order(reverse or forward) in
which the parameters are being read & understood by compilers.
For ex. the following function.
int Add(int p1, int p2, int p3);
The parameters here can be read either in the forward order from p1
till p3 or reverse order from p3 till p1.
Can anyone explain what is the advantage/disadvantage of either of

A theoretical question: Sorry if its a beginner question.
Here is a quote from the MSDN explaning the C/C++ calling convention.. It
demonstrates that the calling function is responsible to clean the stack
pointer and it does it by the command "add esp,8" after returning from
the called function.
My questions:
1. Is the stack pointer common in a certain thread(or process)?
2. How does the called function get the parameters, is it by...

My problem: I need to call (from C code) an arbitrary C library
function, but I don't know until runtime what the function name is,
how many parameters are required, and what the parameters are. I can
use dlopen/whatever to convert the function name into a pointer to
that function, but actually calling it, with the right number of
parameters, isn't easy.
As far as I can see, there are only two solutions:
1) This one is portable. If...

I'm requesting assistance from some of you smart folks out there to
get the managed calls write that meet the specification in the esa.h
for Esa_Init. When I make a call, VS2005 reports
"AccessViolationException" and refers to the 4th parameter
(EsaT_State_Handle). I don't know how to define nor pass this
reference correctly to the legacy DLL. What am I doing wrong? Thanks

Hi,
the following is the definition for calling convention ,which I have
seen in a text book, can anyone give a more detailed explanation in
terms of ANSI - C
"the requirements that a programming system places on how a procedure
is called and how data is passed between a calling program and
procedures are called calling conventions"

Hi there,
This is my first post over here and I hope someone can give me some
guidance.
I'm trying to embed Python into a Visual C++ 2008 application and I'm
getting linker problems. I've compiled a DLL of the Python source code
using the pythoncode VC++ project in the PCbuild folder of the source
download and this works 100% without any warnings etc. I've done this
in Debug and Release mode without any problems.

VC has a __cdecl specifier which allows functions and methods to
be called with varying parameter count.
(I understand this is the default for functions in general but in VC,
instances use another convention unless they have an ellipsis
argument.)
I can force GCC and other compilers to use such a convention by
declaring all methods with an ellipsis, but I'd rather not clutter my
method definitions with these.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
