A smart pointer with reference-counted copy semantics.
The object pointed to is deleted when the last shared_ptr pointing to it is destroyed or reset.

std::shared_ptr< _Tp >::shared_ptr | ( | _Tp1 * | __p | ) | [inline, explicit] |
Construct a shared_ptr that owns the pointer __p.
__p | A pointer that is convertible to element_type*. |
std::bad_alloc,in | which case delete __p is called. |

std::shared_ptr< _Tp >::shared_ptr | ( | _Tp1 * | __p, |
_Deleter | __d | ||

Construct a shared_ptr that owns the pointer __p and the deleter __d.
__p | A pointer. |
__d | A deleter. |
std::bad_alloc,in | which case __d(__p) is called. |
Requirements: _Deleter's copy constructor and destructor must not throw
__shared_ptr will release __p by calling __d(__p)

__p | A null pointer constant. |
__d | A deleter. |
std::bad_alloc,in | which case __d(__p) is called. |
Requirements: _Deleter's copy constructor and destructor must not throw

std::shared_ptr< _Tp >::shared_ptr | ( | const shared_ptr< _Tp1 > & | __r, |
_Tp * | __p | ||
) | [inline] |
Constructs a shared_ptr instance that stores __p and shares ownership with __r.
<strong>r | A shared_ptr. |
__p | A pointer that will remain valid while *r is valid. |
This can be used to construct a shared_ptr
to a sub-object of an object managed by an existing shared_ptr
.

shared_ptr<_Tp1> allocate_shared | ( | const _Alloc & | __a, |
_Args &&... | __args | ||
) | [friend] |
Create an object that is owned by a shared_ptr.
__a | An allocator. |
__args | Arguments for the _Tp object's constructor. |
An | exception thrown from _Alloc::allocate or from the constructor of _Tp. |
A copy of __a will be used to allocate memory for the shared_ptr and the new object.
