Re: [Boost-users] Boost shared pointers, PThreads and void* casts

He might just allocate the shared_ptr on the heap (the dynamic memory allocation will be anyway cheaper than thread creation):

void *thread(void *ptr) { shared_ptr<X> *_p = static_cast<shared_ptr<X>*>(ptr); shared_ptr<X> p = *_p; delete _p; ... }

void creator() { ... pthread_create(&thrid, 0, thread, new shared_ptr<X>(orig_ptr)); ... }

No need for any additional synchronization.

Good point. And certainly much simpler than my solution.
