Functions

addressof	Gets the true address of an object.
align	Returns a pointer to a range of a given size, based on the provided alignment and starting address.
allocate_shared	Creates a shared_ptr to objects that are allocated and constructed for a given type with a specified allocator.
checked_uninitialized_copy	Same as uninitialized_copy but enforces the use of a checked iterator as output iterator.
checked_uninitialized_fill_n	Same as uninitialized_fill_n but enforces the use of a checked iterator as output iterator.
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.
dynamic_pointer_cast	Dynamic cast to shared_ptr.
get_deleter	Get deleter from shared_ptr.
get_pointer_safety	Returns the type of pointer safety assumed by any garbage collector.
get_temporary_buffer	Allocates temporary storage for a sequence of elements that does not exceed a specified number of elements.
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.
owner_less	Allows ownership-based mixed comparisons of shared and weak pointers.
pointer_safety	An enumeration of all the possible return values for get_pointer_safety.
return_temporary_buffer	Deallocates the temporary memory that was allocated using the get_temporary_buffer template function.
static_pointer_cast	Static cast to shared_ptr.
swap	Swap two shared_ptr or weak_ptr objects.
unchecked_uninitialized_copy	Same as uninitialized_copy but allows the use of an unchecked iterator as output iterator when _SECURE_SCL=1 is defined.
unchecked_uninitialized_fill_n	Same as uninitialized_fill_n but allows the use of an unchecked iterator as output iterator when _SECURE_SCL=1 is defined.
undeclare_no_pointers	Informs a garbage collector that the characters in the memory block defined by a base address pointer and block size may now contain traceable pointers.
undeclare_reachable	Informs a garbage_collector that a specified memory location is not reachable.
uninitialized_copy	Copies objects from a specified input range into an uninitialized destination range.
uninitialized_copy_n	Creates a copy of a specified number of elements from an input iterator. The copies are put in a forward iterator.
uninitialized_fill	Copies objects of a specified value into an uninitialized destination range.
uninitialized_fill_n	Copies objects of a specified value into specified number of elements an uninitialized destination range.

Operators

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

allocator	The template class 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 template class 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 template class 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.

Specializations

allocator<void>

A specialization of the template class allocator to type void, defining the only the member types that make sense in this specialized context.
