Example of using CCriticalSection, cont. } main( ) CWinThread *Thread[2]; Thread[0] = AfxBeginThread(ThreadFunction1,LPVOID(NULL)); Thread[1] = AfxBeginThread(ThreadFunction2,LPVOID(NULL)); // Copy to Thread Handle HANDLE hand[2]; for(int i=0;im_hThread; // Wait for complete the child thread , otherwise main thread quit WaitForMultipleObjects(2,hand,TRUE,INFINITE); 44 Note: The Critical section object is same as the Mutex object. But the Critical section object does not allow synchronization with different processes. The critical section is used to synchronize the threads within the process boundary.

Example of using CMutex } Mutex is the synchronization object used to synchronize the threads with more than one process. The Mutex is as the name tells, mutually exclusive. } It is possible to use Mutex instead of critical section. But, the critical section is slightly faster compared to other synchronization objects. CMutex g_m; int g_C; UINT ThreadFunction1(LPVOID lParam) { CSingleLock lock(&g_m); lock.Lock(); g_C++;// Process lock.Unlock(); return 0; } 45 Advanced Windows Network Programming 11/11/12
