NAME
std::experimental::static_pointer_cast,std::experimental::dynamic_pointer_cast, - std::experimental::static_pointer_cast,std::experimental::dynamic_pointer_cast,

Synopsis
   template< class T, class U > (library fundamentals
   std::experimental::shared_ptr<T> static_pointer_cast( (1) TS)
   const std::experimental::shared_ptr<U>& r ) noexcept;
   template< class T, class U > (library fundamentals
   std::experimental::shared_ptr<T> dynamic_pointer_cast( (2) TS)
   const std::experimental::shared_ptr<U>& r ) noexcept;
   template< class T, class U > (library fundamentals
   std::experimental::shared_ptr<T> const_pointer_cast( const (3) TS)
   std::experimental::shared_ptr<U>& r ) noexcept;
   template< class T, class U > (library fundamentals
   std::experimental::shared_ptr<T> reinterpret_pointer_cast( (4) TS)
   const std::experimental::shared_ptr<U>& r ) noexcept;
   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 (but its stored pointer is not necessarily null).
   Otherwise, the new shared_ptr will share ownership with r, except that it is empty
   if the dynamic_cast performed by dynamic_pointer_cast returns a null pointer.
   Let Y be typename std::experimental::shared_ptr<T>::element_type, then the resulting
   std::experimental::shared_ptr's stored pointer will be obtained by calling (in
   respective order):
   1) static_cast<Y*>(r.get()).
   2) dynamic_cast<Y*>(r.get()) (If the result of the dynamic_cast is a null pointer
   value, the returned shared_ptr will be empty).
   3) const_cast<Y*>(r.get()).
   4) reinterpret_cast<Y*>(r.get()).
   The behavior of these functions is undefined unless the corresponding cast from U*
   to T* is well formed:
   1) The behavior is undefined unless static_cast<T*>((U*)nullptr) is well formed.
   2) The behavior is undefined unless dynamic_cast<T*>((U*)nullptr) is well formed.
   3) The behavior is undefined unless const_cast<T*>((U*)nullptr) is well formed.
   4) The behavior is undefined unless reinterpret_cast<T*>((U*)nullptr) is well
   formed.

Parameters
   r - The pointer to convert
