At 

Returns the reference counted interface from the requested location.

Syntax 

ADLX_RESULT     At (const adlx_uint location, IADLXInterface ** ppItem)

Parameters 

  1. [in] location const adlx_uint The location of the returned interface.

  2. [out] ppItem IADLXInterface** The address of a pointer to the returned interface. If the interface is not successfully returned, the method sets dereferenced address *ppItem to nullptr.

Return Value 

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.

Remarks 

IADLXList is a collection of interfaces which runs incrementally from beginning to the end.

The returned interface must be discarded with Release when no longer needed.

Additional Info 

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.
