使用enable_shared_from_this示例

/*测试enable_shared_from_this*/
#include <iostream>
#include <boost/smart_ptr/shared_ptr.hpp>
#include <boost/smart_ptr/weak_ptr.hpp>
#include <boost/smart_ptr/enable_shared_from_this.hpp>
using namespace std;

class TestClass : public enable_shared_from_this<TestClass>
{
public:
private:
    int var;
};

void main()
{
    TestClass *pobj = new TestClass();

    shared_ptr<TestClass> sptr(pobj);
    if (sptr==pobj->shared_from_this())
    {
        cout << "==" << endl;
    }
    else
    {
        cout << "!=" << endl;
    }

    shared_ptr<TestClass> sptr2;
    if (sptr2==pobj->shared_from_this())
    {
        cout << "==" << endl;
    }
    else
    {
        cout << "!=" << endl;
    }
}
