template < class T, class U, class V >
std:: basic_ostream < U, V > & operator << ( std:: basic_ostream < U, V > & os, const std:: shared_ptr < T > & ptr ) ;

将存储在 ptr 中的指针值插入到输出流 os 中。

等价于 os << ptr. get ( ) 。

目录

参数

os - 用于插入 ptr 的 std::basic_ostream 对象
ptr - 将要插入 os 的数据

返回值

os

示例

运行此代码 
#include <iostream>
#include <memory>
class Foo {};
int main()
{
    auto sp = std::make_shared<Foo>();
    std::cout << sp << '\n';
    std::cout << sp.get() << '\n';
}

可能的输出： 

0x6d9028
0x6d9028
