Thread Local Storage

[anthonymoss78]

Hi,

I am trying to write a program that holds a particular unique value to each thread and ability to access this unique value at any time.
I have been using the boost::thread_specific_ptr : but not having much luck..
below is a snapshot:

class LogId

{

public:



LogId(string id)

: id_ (id)

{

}





~LogId()

{

}



string getId()

{

return id_;

}



private:

string id_;



};



static boost::thread_specific_ptr<LogId> ptrId_;







inline void SetTrLogId(const string& id)

{

if (ptrId_.get() == NULL)

{

ptrId_.reset( new LogId(id) );

}

}



inline string getTrLogId()

{

if (ptrId_.get() == NULL)

{

return string("");

}



return ptrId_.get()->getId();

}


And when I call SetTrLogId(..) to set it up .. and then call getTrLogId() in the same thread (I have compared pid values so I know the same thread).. the
ptrId_.get() always returns null.
Can anyone assist please

thanks

I'm unsure of you're goal or what you're wanting. I don't believe that you've used thread_specific_ptr correctly (specifically that its a global), I also don't think there's any real purpose in your wrapper functions.
