How can I pass boost::shared_ptr as a pointer to a Windows Thread function?

Question

How can I pass boost::shared_ptr as a pointer to a Windows Thread function ? assume following code :

test::start()
{
    ....
    _beginthreadex( NULL, 0, &test::threadRun, &shared_from_this(), 0, &threadID );

    ...
    ...
}

/*this is a static function*/
UINT __stdcall test::threadRun( LPVOID lpParam )
{ 
     shared_ptr<test> k = *static_cast< shared_ptr<test>* >(lpParam);
     ...
}

I think this code is incorrect, what is your idea ? how can I do this ?

EDIT : I solved my problem by boost::weak_ptr. check my own answer in this page

Answer 1

I solved my problem by boost::weak_ptr:

test::start()
{
    ....
    shared_ptr<test> shPtr = shared_from_this();
    boost::weak_ptr<test> wPtr=shPtr;
    _beginthreadex( NULL, 0, &test::threadRun, &wPtr, 0, &threadID );

    ...
    ...
}

/*this is a static function*/
UINT __stdcall test::threadRun( LPVOID lpParam )
{ 
shared_ptr<test> k      = static_cast< boost::weak_ptr<test>* >(lpParam)->lock();
     ...
}
