Introduction

std::shared_ptr shares the ownership of the resource. They have two handles: one for the resource and one for the reference counter. By copying a std::shared_ptr, the reference count is increased by one. It is decreased by one if the std::shared_ptr goes out of scope. If the reference counter becomes the value 0, the C++ runtime automatically releases the resource, since there is no std::shared_ptr referencing the resource. The release of the resource occurs exactly when the last ...
