Function

Queries the overflow status of tasks on all streams in the current device and copies the status value to the device memory that you requested. This is an asynchronous API.

Prototype

aclError aclrtGetOverflowStatus(void *outputAddr, size_t outputSize, aclrtStream stream)

Parameters

Parameter	Input/Output	Description
outputAddr	Input/Output	Device memory requested by calling the aclrtMalloc API.
outputSize	Input	Size of the requested device memory, in bytes. The fixed size is 64 bytes.
stream	Input	Stream whose task overflow status will be queried. For details about the type definition, see aclrtStream.

Returns

0 on success; otherwise, failure. For details, see aclError.

Restrictions

For the Ascend 950PR/Ascend 950DT, Atlas A3 training products/Atlas A3 inference products, and Atlas A2 training products/Atlas A2 inference products, the overflow status queried by calling this API is at the process level.
