Example of using CSemaphore - 1 } CSemaphore, CMutex, and CCriticalSection all work in a similar manner. } Semaphore is a thread synchronization object that allows accessing the resource for a count between zero and maximum number of threads. } If the Thread enters the semaphore, the count is incremented. } If the thread completed the work and is removed from the thread queue, the count is decremented. } When the thread count goes to zero, the synchronization object is non-signaled. Otherwise, the thread is signaled. 47 Advanced Windows Network <strong>Programming</strong> 11/11/12
