std::shared_ptr 和普通指針的轉換

相互轉化見示例

struct test
{
     int num;
     string name;
};

test* pTest = new test();
std::shared_ptr<test> ptr_test = std::shared_ptr<test>(pTest); //普通指針轉shared_ptr

std::shared_ptr<test> ptr_test2 = std::make_shared<test>();
test* pTest2 = ptr_test2.get(); //shared_ptr轉普通指針
