WebJan 7, 2024 · Similarly, only the thread that owns a mutex can successfully call the ReleaseMutex function, though any thread can use ReleaseSemaphore to increase the count of a semaphore object. A thread can decrement a semaphore's count more than once by repeatedly specifying the same semaphore object in calls to any of the wait functions. WebThe thread must call ReleaseMutex the same number of times to release ownership of the mutex. If a thread terminates while owning a mutex, the mutex is said to be abandoned. The state of the mutex is set to signaled and the next waiting thread gets ownership. If no one owns the mutex, the state of the mutex is signaled.
