A pointer to a byte array that contains input data for the query. This array always starts with a D3DAUTHENTICATEDCHANNEL_QUERY_INPUT structure. The QueryType member of the structure specifies the query and defines the meaning of the rest of the array.
The size of the pOutput array, in bytes.
A pointer to a byte array that receives the result of the query. This array always starts with a D3DAUTHENTICATEDCHANNEL_QUERY_OUTPUT structure. The meaning of the rest of the array depends on the query.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
