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;
     }
 }
