The Running Threads } The AfxBeginThread function returns immediately; } the return value is a pointer to the newly created thread object. You can use that pointer to suspend and resume the thread (CWinThread::SuspendThread and ResumeThread), but the thread object has no member function to terminate the thread. } Once the worker thread starts, all threads run independently. } Windows divides the time among the threads (and among the threads that belong to other processes) according to their priority. } If the main thread is waiting for a message, the compute thread can still run. 15 Advanced Windows Network <strong>Programming</strong> 11/11/12
