2020-02-23 17:11 Mutex vs Semaphore. A mutex provides mutual exclusion, either producer or consumer can have the key (mutex) and proceed with their work. As long as the buffer is filled by producer, the consumer needs to wait, and vice versa. At any point of time, only one thread can work with the entire buffer. The concept can be generalized using semaphore.
Use CreateSemaphore or CreateSemaphoreEx to create a named semaphore. You can use the name to access the semaphore from other locations by calling CreateSemaphore a second time. windows mutex semaphore
Semaphore Objects. The driver can use the device extension of a drivercreated device object, the controller extension if it uses a controller object, or nonpaged pool allocated by the driver.

Differences between mutex and semaphore (I never worked with CriticalSection): When using condition variables, its lock must be a mutex. When using more than 1 available resources, you must use a semaphore initialized with the number of available resources, so Oct 20, 2011 If you can, use a critical section rather than a mutex because they are simpler to use and more efficient. But they have the same semantics in that they only protect code inside the locking block. Note: Jerry has pointer out some other problems, but I've concentrated on the high level trheading and serialization concerns. Mutex Objects. A mutex object is a synchronization object whose state is set to signaled when it is not owned by any thread, and nonsignaled when it is owned. Only one thread at a time can own a mutex object, whose name comes from the fact that it is useful in coordinating mutually exclusive access to a shared resource. windows mutex semaphore How can the answer be improved? The count on the semaphore is full, and when thread A eventually calls Release, a is thrown. Named Semaphores. The Windows operating system allows semaphores to have names. A named semaphore is system wide. That is, once the named semaphore is created, it is visible to all threads in all processes. Semaphore Objects. A semaphore object is a synchronization object that maintains a count between zero and a specified maximum value. The count is decremented each time a thread completes a wait for the semaphore object and incremented each time a thread releases the semaphore. On Windows, there are two differences between mutexes and binary semaphores: A mutex can only be released by the thread which has ownership, i. e. A thread can call a
