FreeAllEvent

Applicability

Function Usage

Releases all synchronization events requested in a queue. The buffers allocated to the queue are associated with the event IDs of the synchronization events. The number of synchronization events is limited. If the number of queue buffers used at the same time exceeds the limit, no more queues can be requested. After this API is called to release the events in the queue, you can request a queue again. For details, see TQue Buffer Limit.

__aicore__ inline void FreeAllEvent()

Parameters

None

Constraints

This API does not support inplace tensor operations. This means depth of TQue is set to 0.

Returns

None
