Initialize shared_ptr passed by the member function parameter

Question

Hope someone can help me deal with this situation. Here is the problem. I have a shared library (.so, .dll, .dynlib). Inside this library there is some kind of factory class that creates objects. For example, my method looked like this:

class RenderSystem {
    public:
        int createTexture(Texture** texture, ...);
        ....
}

The method createTexturein the class is RenderSystemas follows:

int createTexture(Texture** texture, ...) {
    ....
    *texture = new ...
    return someErrorCode;
}

He created an instance Textureand passed a pointer to a parameter Texture. We know that instances created in a shared library must be destroyed the same way. Therefore, I had methods that removed / destroyed these textures.

shared_ptr , . a std::shared_ptr<Texture> . std::shared_ptr<Texture> std::shared_ptr<Texutre>? :

int createTexture(std::shared_ptr<Texture>& texture, ...) {
    ....
    texture = std::shared_ptr<....>(...) or std::make_shared<...>(..);
    return someErrorCode;
}
