std::shared_ptr::operator*, std::shared_ptr::operator->

T& operator*() const noexcept;

T* operator->() const noexcept;

Dereferences the stored pointer. The behavior is undefined if the stored pointer is null.

Parameters

(none).

Return value

Remarks

When T is a (possibly cv-qualified) void, it is unspecified whether function (1) is declared.

If either function is declared despite being unspecified, it is unspecified what its return type is, except that the declaration (although not necessarily the definition) of the function is guaranteed to be legal. This makes it possible to instantiate std::shared_ptr<void>.

Example

#include <iostream>
#include <memory>
 
struct Foo
{
   Foo(int in) : a(in) {}
   void print() const
   {
      std::cout << "a = " << a << '\n';
   }
   int a;
};
 
int main()
{
   auto ptr = std::make_shared<Foo>(10);
   ptr->print();
   (*ptr).print();
}

a = 10
a = 10
