[Boost-users] "Different" use of shared_ptr/weak_ptr

Hi all! 

I am trying to use boost smart pointers for some multithreaded work in the following way: 

1. I use shared_ptr to wrap stuff in thread 1 
2. I create weak_ptr-s in thread 1 and pass them to thread 2 
3. in thread 2, I lock my weak_ptr-s and use stuff I get from there 
4. in thread 1 I may destroy my shared_ptr 
5. next time I want to lock my weak_ptr, I get NULL and can't use stuff 

Basically, my idea is to use weak_ptr as sort of transport mechanism 
between threads, but with "stuff destroyed detection".

I did some tryouts and this seems to be OK. However, I'd like to get 
some more authorative advice :-)) Can I do that? If no, why not, or, what would you suggest? 

Thanks, 

Goran.
