std::shared...::owner_hash(3) C++ Standard Libarystd::shared...::owner_hash(3) NAME std::shared_ptr::owner_hash - std::shared_ptr::owner_hash Synopsis std::size_t owner_hash() const noexcept; (since C++26) Returns an unspecified value such that for any object other where owner_equal(other) is true, owner_hash() == other.owner_hash() is true. This hashing is used to make shared and weak pointers usable as keys in unordered associative containers, typically through std::owner_hash. Return value A value that is identical for any std::shared_ptr or std::weak_ptr object sharing the same ownership.
