I don't think so

Once ypu return the object, it is accessible by whoever called the function

No matter if it's a "private"

At least in my C++11 programs it works

Dunno if something happened in cpp14/17

I use this for mutexes, if I need to lock a mutex outside a class

If have a class like this class Foo { Object obj; public: void Get(Object & obj) {} }; You need to pass an obj to get, however you cannot use the member of the class

whereas Object& get() returns the member object

No

void Get(Object& obj) { obj = obj; }

obj=mobj;

yes, but where does the parameter come from?

The reference parameter is meant to be OUT

It would be a dummy object

I dunno

I never did it that way

That's what I meant :) I think there is no way to make them exactly the same

Well yeah calling them is different

But both can return the same thing

void Get(Object& obj) { obj = obj; }

However, this would impose the cost of calling the copy constructor and modified the 'OUT' object would not be reflected inside the class

Yep

I dislike C++ because of references

In C you could just initialize the it as NULL in calling function, and pass a pointer to a pointer

well ofc that can be achieved in cpp too, but it is "ugly" cpp :D

Are you a Finn too, btw?

And C++11 introduced R-Value References what did not help to make them more comprehensible :D

No, I am from Germany

ok, was just wondering, Olli is a Finnish name too

However, this would impose the cost of calling the copy constructor and modified the 'OUT' object would not be reflected inside the class

I played a little bit with "compiler explorer" regarding returning objects ( clang almost always succeeds in optimizing everything out ) , you can try for yourself with different implementation of "Object" here: https://godbolt.org/g/jp3NLi

returning Object is almost always better.

returning Object is almost always better.

As always when writing C++, I think it depends on what you want to do :D

Good night

As always when writing C++, I think it depends on what you want to do :D

I would love to return a mutex and then find out it returns a ref in some compilers and a copy in others :D

Like for some data types its not a big deal to return a copy

I would love to return a mutex and then find out it returns a ref in some compilers and a copy in others :D

Compiler sould never do anything that changes outcome of the operation. It's a bug if that's happens

mm :)

Why

Hello. Not sure if anyone here has experience using Vugen. I'm looking for some help using vugen v12. Is there a way you can save the html of a page and validate it during a web_custom_request? The web_reg_find function would let me validate current html elements, but I want to know if a new element appears like a button.

Hello all

How are you today ?

Hi

What use of this-> ?

What use of this-> ?

When struct/class is a pointer

Or you got a pointer to a struct/class

When struct/class is a pointer

Oh thanks

I always used to get p. and p-> mixed up

I always used to get p. and p-> mixed up

Ya me too confius with object.

I means p. .
