[Function Discovery is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]
This interface implements the asynchronous query for a function instance based on category and subcategory. A pointer to this interface is returned when the query is created by the client program.
The IFunctionInstanceQuery interface has these methods.
|IFunctionInstanceQuery::Execute||Performs the query defined by IFunctionDiscovery::CreateInstanceQuery.|
The Execute method must be invoked by the client program before any data can be retrieved from the query object.
