const_pointer_cast | Const cast to shared_ptr . |
declare_no_pointers | Informs a garbage collector that the characters starting at a specified address and falling within the indicated block size contain no traceable pointers. |
declare_reachable | Informs garbage collection that the indicated address is to allocated storage and is reachable. |
default_delete | Deletes objects allocated with operator new . Suitable for use with unique_ptr . |

make_shared | Creates and returns a shared_ptr that points to the allocated object constructed from zero or more arguments using the default allocator. |
make_unique | Creates and returns a unique_ptr that points to the allocated object constructed from zero or more arguments. |
pointer_safety | An enumeration of all the possible return values for get_pointer_safety . |

Operators
Name | Description |
---|---|
operator!= | Tests for inequality between allocator objects of a specified class. |
operator== | Tests for equality between allocator objects of a specified class. |
operator>= | Tests for one allocator object being greater than or equal to a second allocator object, of a specified class. |
operator< | Tests for one object being less than a second object of a specified class. |
operator<= | Tests for one object being less than or equal to a second object of a specified class. |
operator> | Tests for one object being greater than a second object of a specified class. |
operator<< | shared_ptr inserter. |
Classes
Name | Description |
---|---|
allocator | The class template describes an object that manages storage allocation and freeing for arrays of objects of type Type. |
allocator_traits | Describes an object that determines all the information that is needed by an allocator-enabled container. |
auto_ptr | The class template describes an object that stores a pointer to an allocated object of type Type * that ensures the object to which it points gets deleted when its enclosing auto_ptr gets destroyed. |
bad_weak_ptr | Reports bad weak_ptr exception. |
enabled_shared_from_this | Helps generate a shared_ptr . |
pointer_traits | Supplies information that is needed by an object of type allocator_traits to describe an allocator with pointer type Ptr . |
raw_storage_iterator | An adaptor class that is provided to enable algorithms to store their results into uninitialized memory. |
shared_ptr | Wraps a reference-counted smart pointer around a dynamically allocated object. |
unique_ptr | Stores a pointer to an owned object. The pointer is owned by no other unique_ptr . The unique_ptr is destroyed when the owner is destroyed. |
weak_ptr | Wraps a weakly linked pointer. |
Structures
Name | Description |
---|---|
allocator_arg_t | |
default_delete | |
hash | Provides overloads specialized for unique_ptr and shared_ptr . |
owner_less | Allows ownership-based mixed comparisons of shared and weak pointers. |
uses_allocator |
Specializations
Name | Description |
---|---|
allocator<void> | A specialization of the class template allocator to type void , defining only the member types that make sense in this specialized context. |
