Hi!
What about using thread specific pointer?

http://www.boost.org/doc/html/thread_specific_ptr.html

Take a look at this example:

http://www-eleves-isia.cma.fr/documentation/BoostDoc/boost_1_29_0/libs/thread/example/tss.cpp

And remember, that you can pass to your thread function any data, using smth. similar like:

############## UNTESTED CODE #################

boost::thread_specific_ptr<int>      thread_id;

void thread_proc(int id)
{
   thread_id.reset(new int(id)); // initialize the thread's storage

   //do some stuff
}

int main(int argc, char* argv[])
{
   boost::thread_group threads;
   for (int i=0; i<5; ++i)
      threads.create_thread( std::bind1st( std::ptr_fun(&thread_proc) , i) );
   threads.join_all();
}

############## END OF UNTESTED CODE #################
