operator== <memory>

shared_ptr equal comparison.

template<class Ty1, class Ty2>
    bool operator==(const shared_ptr<Ty1>& left;,
        const shared_ptr<Ty2>& right);

Parameters

• Ty1
  The type controlled by the left shared pointer.

• Ty2
  The type controlled by the right shared pointer.

• left
  The left shared pointer.

• right
  The right shared pointer.

Remarks

The template operator returns left.get() == right.get().

Example

// std_tr1__memory__operator_eq.cpp 
// compile with: /EHsc 
#include <memory> 
#include <iostream> 
 
int main() 
    { 
    std::tr1::shared_ptr<int> sp0(new int(0)); 
    std::tr1::shared_ptr<int> sp1(new int(0)); 
 
    std::cout << "sp0 == sp0 == " << std::boolalpha 
        << (sp0 == sp0) << std::endl; 
    std::cout << "sp0 == sp1 == " << std::boolalpha 
        << (sp0 == sp1) << std::endl; 
 
    return (0); 
    } 
 

sp0 == sp0 == true sp0 == sp1 == false
