This function releases all resources used by a critical section object that is not owned.
Deleting a critical section object releases all system resources used by the object. Once deleted, the critical section object cannot be specified in the EnterCriticalSection, TryEnterCriticalSection, or LeaveCriticalSection function. If a critical section is deleted while it is still owned, the state of the threads waiting for ownership of the deleted critical section is undefined.
Each object type, such as memory maps, semaphores, events, message queues, mutexes, and watchdog timers, has its own separate namespace. Empty strings, "", are handled as named objects. On Windows desktop-based platforms, synchronization objects all share the same namespace.
