Code examples

The following code example fails the check and will give a warning:

#include <memory> 

int example() 
{ 
    auto sp = std::make_shared<int>(5);
    return (sp.unique()) ? 0 : 1;
}

The following code example passes the check and will not give a warning about this issue:

#include <memory> 

int example() 
{ 
    auto sp = std::make_shared<int>(5);
    return (sp.use_count() == 1) ? 0 : 1;
}
