Creates a new instance of std::experimental::shared_ptr whose stored pointer is obtained from r's stored pointer using a cast expression. If r is empty, so is the new shared_ptr
Otherwise, the new shared_ptr will share ownership with r, except that it is empty if the dynamic_cast performed by dynamic_pointer_cast
Let Y be
typename
std::experimental::shared_ptr
<T>
::
element_type
, then the resulting std::experimental::shared_ptr
dynamic_cast is a null pointer value, the returned shared_ptr
The behavior of these functions is undefined unless the corresponding cast from U* to T* is well formed:
Parameters
| r | - | the pointer to convert |
