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. 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 .
