Chapter 1. Boost.SmartPointers - Shared Ownership

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. Webb5 aug. 2024 · Smart pointers are objects which store pointers to dynamically allocated (heap) objects. They behave much like built-in C++ pointers except that they automatically delete the object pointed to at the appropriate time. Smart pointers are particularly useful in the face of exceptions as they ensure proper destruction of dynamically allocated objects.
