aclrtSetStreamConfigOpt

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Description

Sets the value of each attribute in the stream configuration object.

Restrictions

This API must be used together with other APIs to create a stream. The API call sequence is as follows:
  1. Call aclrtCreateStreamConfigHandle to create a stream configuration object.
  2. Call aclrtSetStreamConfigOpt for multiple times to set the value of each attribute in the configuration object.
  3. Call aclrtCreateStreamV2 to create a stream.
  4. After the stream is used, call aclrtDestroyStreamConfigHandle to destroy the stream configuration object and call aclrtDestroyStream to destroy the stream.

Prototype

aclError aclrtSetStreamConfigOpt(aclrtStreamConfigHandle *handle, aclrtStreamConfigAttr attr, const void *attrValue, size_t valueSize)

Parameters

Parameter

Input/Output

Description

handle

Output

Pointer to the stream configuration object. Call aclrtCreateStreamConfigHandle to create an object in advance.

attr

Input

Attribute to set.

attrValue

Input

Pointer to the attr value to set.

If the attribute value itself is a pointer, pass the address of the pointer.

valueSize

Input

Data length of attrValue.

You can use the sizeof(*attrValue) function in the C/C++ standard library to query the data length.

Returns

The value 0 indicates success, and other values indicate failure. For details, see aclError.
