WebbThis functionality is supported by boost::make_shared (until C++20) code such as f(std::shared_ptr(new int(42)), g()) can cause a memory leak if g gets called after new int(42) and throws an exception, while f(std::make_shared(42), g()) is safe, since two function calls are never interleaved .

How to implement user defined Shared Pointers in C++

WebbThe stored pointer points to the object the shared_ptr object dereferences to, which is generally the same as its owned pointer (the pointer deleted when destroyed). They may be different if the shared_ptr object is an alias (i.e., alias-constructed objects and their copies). The function returns the same as get () !=0.

WebbReturns the number of shared_ptr objects that share ownership over the same pointer as this object (including it). If this is an empty shared_ptr, the function returns zero. Library implementations are not required to keep a count of any particular set of owners, and thus it may not be efficient to call this function.
