std::shared_ptr -
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
shared_ptr - C++ Reference
std::shared_ptr. Objects of shared_ptr types have the ability of taking ownership of a pointer and share that ownership: once they take ownership, the group of owners of a pointer become responsible for its deletion when the last one of them releases that ownership.
c++ - std::shared_ptr of this - Stack Overflow
There is std::enable_shared_from_this just for this purpose. You inherit from it and you can call .shared_from_this() from inside the class. Also, you are creating circular dependencies here that can lead to resource leaks. That can be resolved with the use of std::weak_ptr. So your code might look...

std::shared_ptr is a smart pointer that retains shared ownership of an object through a pointer. Constructing a new shared_ptr using the raw underlying pointer owned by another shared_ptr leads to undefined behavior. std::shared_ptr may be used with an incomplete type T. However, the...

13) Constructs a shared_ptr which manages the object currently managed by r. The deleter associated with r is stored for future deletion of the managed object. r manages no object after the call. This overload doesn't participate in overload resolution if std::unique_ptr<Y, Deleter...
M.7 — std::shared_ptr | Learn C++
Internally, std::shared_ptr keeps track of how many std::shared_ptr are sharing the resource. As long as at least one std::shared_ptr is pointing to the resource, the resource will not be deallocated, even if individual std::shared_ptr are destroyed.
Exploring std::shared_ptr | Shahar Mike's Web Spot
Unlike unique_ptr , shared_ptr can be shared. This means that multiple instances of shared_ptr<T> pointing to the same instance of T can co-exist. shared_ptr must have at least 2 pointers, so it's bigger than a raw pointer. It also guarantees thread-safety for all methods as long as each thread has...
C++ - Sharing ownership (std::shared_ptr) | c++ Tutorial
The class template std::shared_ptr defines a shared pointer that is able to share ownership of an object with other shared pointers. When this count reaches zero, either through the destruction or reassignment of the last std::shared_ptr instance, the object is automatically destroyed.

std::make_shared makes one memory allocation for both the object and data structure required for reference counting i.e. new operator will called only once. Detaching the associated Raw Pointer. To make shared_ptr object de-attach its attached pointer call reset() method i.e.
Using custom deleter with shared_ptr and unique_ptr in C++ | Medium
std::shared_ptr. You can pass any callable thing (lambda, functor) as deleter while constructing a shared pointer in the constructor as an additional One of the overloads of shared_ptr construction. thus specifying custom deleter with std::shared_ptr is comparatively easy. On ref count reaches zero...
shared_ptr - 1.61.0
shared_ptr deletes the exact pointer that has been passed at construction time, complete with its original type, regardless of the template parameter. shared_ptr is now part of the C++11 Standard, as std::shared_ptr. Starting with Boost release 1.53, shared_ptr can be used to hold a pointer to a...

Specialities of std::shared_ptr -
std::shared_ptr as function argument. Therefore, we are dealing with the quite interesting question. The function byCopy takes its std::shared_ptr by copy. Therefore, the reference count is increased in the function body to 2 and afterwards decreased to 1. The question is now.
Shared ptr
Shared ptr : A minimal light and fast shared_ptr implementation designed to handle cases where boost/std::shared_ptr are not available. To use this shared_ptr implementation, you only need to include the shared_ptr.hpp file from the source code of your projects. License.

The C++11 std::shared_ptr<T> is a shared ownership smart pointer type. Several shared_ptr instances can share the management of an object's lifetime through a common control block. The managed object is deleted when the last owning shared_ptr is destroyed (or is made to point to...
std::tr1::shared_ptr tutorial | Anteru's Blog
std::tr1::shared_ptr is part of the TR1 additions to the C++ STL. With GCC, it is available either through #include <tr1/memory> (GCC 4.1) or #include <memory> (GCC 4.3), the latter form works also on Windows (with VS2008 SP1). If you want to be portable, try Boost, which uses the vendor-provided...
