Syntax C++ PDH_STATUS PdhOpenQueryH( __in PDH_HLOG hDataSource, __in DWORD_PTR dwUserData, __out PDH_HQUERY *phQuery ); Parameters hDataSource [in] Handle to a data source returned by the PdhBindInputDataSource function. dwUserData [in] User-defined value to associate with this query. To retrieve the user data later, call the PdhGetCounterInfo function and access the dwQueryUserData member of PDH_COUNTER_INFO . phQuery [out] Handle to the query. You use this handle in subsequent calls. Return Value If the function succeeds, it returns ERROR_SUCCESS. If the function fails, the return value is a system error code or a PDH error code .
