Gets the reference counted GPU metrics interface of a metric sample.
ADLX_RESULT GetGPUMetrics (IADLXGPU * pGPU, IADLXGPUMetrics ** ppGPUMetrics)
[in]pGPU IADLXGPU* The pointer to a variable where IADLXGPU interface is returned.
[out]ppGPUMetrics IADLXGPUMetrics** The address of a pointer to the returned interface. If the interface is not successfully returned, the method sets the dereferenced address *ppGPUMetrics to nullptr.
If the interface is successfully returned, ADLX_OK is returned.
If the interface is not successfully returned, 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.
