Hi, booster, I am using boost.thread in Windows with VC6, it's quite handy and useful. I found it's better if the library can add 2 additional methods. One is the typedef platform_dependent thread_id_type; thread_id_type id() const ; sometimes I want to know what thread is really in the log file. so I can write this: std::cout << thread().id() << std::endl; another one is a way to return the raw thread_handle. typedef platform_dependent thread_handle thread_handle handle() const ; by this, I can suspend, terminate the thread in Windows, or in Posix platform using #ifdef. For example; boost::thread t(...); #ifdef WINDOWS ::TerminateThread(t.handle()); #endif Is this doable? Thanks.
