## Detailed Description

Smart pointers, etc.

## Function Documentation

template<typename _Tp , typename _Alloc , typename... _Args>

shared_ptr<_Tp> std::allocate_shared | ( | const _Alloc & | __a,
|  | _Args &&... | __args
| ) |  |

inline

Create an object that is owned by a shared_ptr.

Parameters

  __a | An allocator.
  __args | Arguments for the _Tp object's constructor.

Returns
  A shared_ptr that owns the newly created object.

Exceptions

  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.

template<typename _Tp , typename... _Args>

shared_ptr<_Tp> std::make_shared | ( | _Args &&... | __args | ) |

inline

Create an object that is owned by a shared_ptr.

Parameters

  __args | Arguments for the _Tp object's constructor.

Returns
  A shared_ptr that owns the newly created object.

Exceptions

  std::bad_alloc,or | an exception thrown from the constructor of _Tp.
