Hi,
I'm looking for a way, to identify a boost::thread from inside the thread. The background is, that I want to log into a global logger, which has to know from which thread the message was sent.
I have thought at using the pointer of the class as an identifier, but that won't work if two threads are from the same class. Maybe it is possible to save a pointer to the member methods???
Kind Regards Torsten

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/threa... 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 ################# With Kind Regards, Ovanes Markarian
