PAPI_query_named_event() asks the PAPI library if the PAPI named event can be counted on this architecture\&. If the event CAN be counted, the function returns PAPI_OK\&. If the event CANNOT be counted, the function returns an error code\&. This function also can be used to check the syntax of native and user events\&.
