share_ptr 智能指针用法示例

#include <boost/shared_ptr.hpp>
#include <iostream>
using namespace std ;
class connection
{
public :
    connection()
    {
    }
    virtual ~connection()
    {
        cout << " connection is over \n";
    }
    void done()
    {
        cout <<  "do is running \n";
    }
};

#include <stdlib.h>
#include <boost/smart_ptr/shared_ptr.hpp>

int main(int argc, char** argv) {

    boost::shared_ptr < connection > p ( new connection());

    p->done();
    p.reset(new connection());
   
    cout << "main is over \n";
    //

    return (EXIT_SUCCESS);
}
