How to save image data in shared pointer

edit

what do you need it for ?

who will own the data in which step of your program ?

will it need copies, and when ?

@berak thank you very much for your fast reply.

Actually, one module of our OpenCV software will be developed by another company and they want me to pass newFrame image to their software module in following format:

Void PartnerComanyModule (std::shared_ptr<char>& newFrame_dat, int typeOfnewFrame, cv::Size src_size.widthOfNewFrame, cv::Size src_size.heigthOfNewFrame);

So that later in their module they can reconstruct image using following instruction.

cv::Mat src(src_size, type, (void*)src_data.get());

So can you please inform me how can I convert image in Mat object to std::shared_ptr<char>& newFrame_dat ?

Please inform me if you need any other information from me.

Many thanks :)

i just deleted the prev. answer, because it was wrong.

never thought about shared_ptr deleting objects.

can you take a look at https://en.cppreference.com/w/cpp/mem... ?

std::shared_ptr is a smart pointer that retains shared ownership of an object through a pointer. Several shared_ptr objects may own the same object. The object is destroyed and its memory deallocated when either of the following happens:

    the last remaining shared_ptr owning the object is destroyed;
    the last remaining shared_ptr owning the object is assigned another pointer via operator= or reset(). 

The object is destroyed using delete-expression or a custom deleter that is supplied to shared_ptr during construction.

you have 2 concurring refcounted pixel containers, and that's a terrible idea
