Gets the reference counted main interface to the Display domain.
ADLX_RESULT GetDisplaysServices (IADLXDisplayServices ** ppDispServices)
[out]ppDispServices IADLXDisplayServices** The address of a pointer to the returned interface. If the interface is not successfully returned, the method sets the dereferenced address *ppDispServices to nullptr.
If the interface is successfully returned, ADLX_OK is returned.
If the interface is not 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.
