FreeAllEvent

Function Usage

Releases all events in a queue. It is an extra protection mechanism to prevent mismatch of synchronization events. You are advised to ensure that the AllocTensor/FreeTensor and EnQue/DeQue are used in pairs. If they are used in pairs, you do not need to call FreeAllEvent.
