no shit sherlock, you implement those classes urself and set the right offsets at runtime

i don't think ur gonna target win7 nowadays lol

is it that you recompile the driver for each windows build or do it at runtime is whatever suits you

Hey, everybody. A small question.
how to declare a static variable in a class function? it should be universal for each object
I may be a bit wrong in the code, but the essence should be clear
Simple Sorcerer
class A{
A(){
<static> int val; // &val = universal
printf( val );
}
};
int main(){
A a1; // &val<1>
A a2; // need &val<2> != &val<1>
}
Simple Sorcerer
Of course you could just declare everything in private, but for me this option would be more convenient

I may be a bit wrong in the code, but the essence should be clear
What do you mean a class function? Are you thinking of closures or limiting the static variable access just to a specific member variable?
Manav
class A{
A(){
<static> int val; // &val = universal
printf( val );
}
};
int main(){
A a1; // &val<1>
A a2; // need &val<2> != &val<1>
}
Also it is not immediately obvious what you're trying to do
Manav
If it's a static member variable you want, you can do:
class A { static int val; }
int A::val = 42; // required sepearate definition from declaration
Simple Sorcerer
Also it is not immediately obvious what you're trying to do
I need a variable to be available only within one object and destroyed together with it.
A crude example is to simply declare a variable: int val;
But I need to allocate memory only once

Hmm, your words contradict each other.
One variable per object (per instance) means a member variable.
And if you want one variable per class then that's a static member variable which i just showed you above.

Here I have shown the memory allocation. it is very bad what I have done. but this is what I need. I need to initialise an expensive variable once for several functions, it would be more convenient to use one name for each function.
But the problem with static is that I checked how memory is allocated, and if I create a second object, the variable with static also points to the same memory.
Manav
that's what static means in C++ when it's used inside class definition.
Manav
you use static for a member variable then it becomes unbounded to class instances, they can be initialized, in case of static data members (different from static member variables, but for your case it's the same) even if you don't have any object of the class.
Manav
just rename the variable as such, and store a pointer in the class. You can use typedefs if you want them to have a different names in each function.

But the problem with static is that I checked how memory is allocated, and if I create a second object, the variable with static also points to the same memory.
My problem would be solved by defining variables in the "private" memory area as:
int val1, val2, val3;
but you have to agree that this doesn't look very good
Manav
Manav
can you explain what the lifetime of val1, val2 and val3 look like? you have three mallocs() so there are three different objects
Simple Sorcerer
Simple Sorcerer
Manav
malloc = bad example
can you share an example which looks more to what you're trying to do, or just paste the snippet of your actual code (if you're fine with sharing code to public places)
Manav
your malloc() example tells me that you want three static objects for the class
Simple Sorcerer

it's very big and ugly. So I've made a little example that everyone will understand.
Simple Sorcerer
Manav

well you haven't clearly told us what you want, that example is all i have.
Simple Sorcerer
let's go to the beginning. I need
int val
but that memory should be allocated for it only once within one object of a class.
new class => fun => int val => delete class => delete val
new class => fun => int val => delete class => delete val
Simple Sorcerer
I think this example is even worse than the ones above.

int val
but that memory should be allocated for it only once within one object of a class.
new class => fun => int val => delete class => delete val
new class => fun => int val => delete class => delete val
okay i'll ask the questions you tell me if you want that or not
Manav
you have a variable that's associated to a class in some way, yes?
Simple Sorcerer
you have a variable that's associated to a class in some way, yes?
variable = private variable
Manav
it needs to be associted to class, yes?
Simple Sorcerer
no
Simple Sorcerer
It's essentially unnecessary for the class to work
Simple Sorcerer
no
Simple Sorcerer
yes......
Manav
okay
Manav
now to it's lifetime
Manav
does the variable has independent lifetime from the objects of the class?
Simple Sorcerer
yes......
but this variable is not used anywhere except in one function (each function has its own variable, looks like a simple int val declaration)
Manav
but this variable is not used anywhere except in one function (each function has its own variable, looks like a simple int val declaration)
okay so you want to limit visibility of the variable in that specific function?
Simple Sorcerer
yes
Manav
you want that to be static? one allocation for all objects of that class
Simple Sorcerer
no
Simple Sorcerer
local variable = one object
but one malloc for variable
Manav
local variable = one object
but one malloc for variable
this is the part that doesn't make sense to me
Manav
lemme share code, wait a second
Simple Sorcerer
void fun(){
int val;
// using val .....
}
Simple Sorcerer
but val = variable is created once

with code formatting i feel like this bot hinders sharing code than actually helping
It would be great if it could turn only large code into a file.

static will have just one var1 for all a1, a2 and a3
