Function Usage

Queries whether there are enqueued tensors in the queue.

Prototype

      
           __aicore__ inline bool HasTensorInQue()

Parameters

None

Constraints

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

Returns

true: Enqueued tensors exist in the queue.
false: The queue is completely idle.

Example

      
           // Determine whether there are enqueued tensors in the current queue based on VacantInQue. The depth of the current queue is 4. If there is no memory enqueuing action, the return is false.
AscendC::TPipe pipe;
AscendC::TQue<AscendC::TPosition::VECOUT, 4> que;
int num = 4;
int len = 1024;
pipe.InitBuffer(que, num, len);
bool ret = que.HasTensorInQue();
