Returns the reference counted interface at the requested location.
ADLX_RESULT At (const adlx_uint location, IADLXManualFanTuningState ** ppItem)
[in]location const adlx_uint The location of the requested interface.
[out]ppItem IADLXManualFanTuningState** The address of a pointer to the returned interface. If the interface is not successfully returned then the method sets the dereferenced address *ppItem to nullptr.
If the location is within the list bounds, ADLX_OK is returned.
If the location is not within the list bounds, an error code is returned.
Refer to ADLX_RESULT for success codes and error codes.
The returned interface must be discarded with Release when it is no longer needed.
In C++, when using ADLX interfaces as smart pointers, there is no need to call Release because smart pointers call it in their internal implementation.
