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

This API must be used together with other APIs to create a stream. The API call sequence is as follows:

Call aclrtCreateStreamConfigHandle to create a stream configuration object.
Call aclrtSetStreamConfigOpt multiple times to set the value of each attribute in the configuration object.
Call aclrtCreateStreamV2 to create a stream.
After the stream is used, call aclrtDestroyStreamConfigHandle to destroy the stream configuration object and call aclrtDestroyStream to destroy the stream.

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

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.

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