Does anyone have any code handy (or know what a good direction for me to
head in), to call functions, if you have an address of the function, its
declspec (for my app, it's limited to _stdcall and thiscall), and what
parameters it expects? I know all about the argument ordering on the stack,
but I don't really know enough ASM to work with it. Does anyone out there
know of a cheap way to do it in more standardized C++? (efficiency doesn't...

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

Hi all,
anybody knows if there is a (standard, portable) way to dinamically build
a list of parameters to call a C function? Something like va_start & co,
but to be used on the calling side?
In other words, suppose that I have a generic pointer :
void * f_ptr;
I know that this pointer points to a fuction. I also know the function

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...

The implementation of classes with virtual functions is conceptually easy to
understand: they use vtables. Which begs the question about POD structs: how
are they associated with their member functions in common implementations?
And where is the 'this' ptr tucked away at for POD structs with member
functions?

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"

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,...
