If you don't know what a vector is and how to use it and what to use it for — it's not my problem, it's yours

Are you blind or what? i told you THE EXACT REASON why it's not correct
You gave me that reason post factum. That's pretty much what relegion does, it explains events post factum

(you can literally put RAII resources into vector.. but why "another process"?

At least I know what a vector is lol
I'm really curious, would you mind to share your definition of vector?

std::vector is a sequence container that encapsulates dynamic size arrays.

So it's banch of memory, isn't it?

I can say the same to you, can't I?

You have no clue how C++ memory model works

Seems more than you :)

If you think that a vector is just a bunch of memory

If you want to use stl container as buffer, maybe string is a better choice, at least it has defined behavior for .data()

Really where did you find ANYTHING related to memory model in these comments?

You know the problem here is: my statement is correct (vector is a continuous peace of memory). But your statement about memory model does not have anything related to this topic

It is not correct

Ok, continues peace of memory plus O(1) additional info

Still not correct

Vector is a contiguous container of objects

It's not about memory

Everything in C++ is an object (except references and functions)
Sandro
It could but not.... You can represent or as a contiguous byte of memory, but physically can be discontinuous...

Even this was UB until C++20
int* a = (int*)malloc(sizeof(int));
*a = 5;

But if you want to share resources between processes use tools that were DESIGNED for that

Vector is not designed to be shared
⚛ Hz
Wait, it is about sharing memory across process, I probably know where the dispute is

C++ doesn't even have a definition of process

There is no such a term in c++ as a process

In Linux or Windows or any sane OS it exists

Your example is not correct, because you used a vector for a case it's not designed for
Do you understand it?

Signals are another example of IPC

So, technically some sort of external effects exist in c++

What signals exist in a standard C++?

Unless you are in multiple processes there should not be any issues

This is signal handler. For OS signals. not C++ signals.
It's more POSIX related than C++.

Yeah, I mean it's only handler. It's not like you can send a signal or something and have async flow. I was thinking more like https://theboostcpplibraries.com/boost.signals2-signals
Or https://doc.qt.io/qt-5/signalsandslots.html

Async/await exist in c++ 20
Yes, co-routines and signal/slot are not the same. With proper signals/slot you can easily create asynchronous observer pattern. Co-routines is something different.

Any idea about project in C
MRT
The variable defined by &, means variable is reference
So what does this mean?
const int& x = 50;
We defined the reference variable with a number. What is this variable referring to now?a

One can give an example of this book sentence with a code (It is important to remember that there
is no guarantee that an object pointed to by a pointer to const won’t change.)
