| 释义 | PdhCollectQueryDataWithTime 语法： C++ PDH_STATUS PdhCollectQueryDataWithTime( __inout PDH_HQUERY hQuery, __out LONGLONG *pllTimeStamp ); PdhCollectQueryDataWithTime功能 目前的原料收集在指定的查询和更新的每个计数器的状态代码的所有计数器的数据值。 参数 hQuery [ in , out ] 处理的查询您要收集数据。该PdhOpenQuery函数返回此句柄。 pllTimeStamp [out] 时间戳当查询中的第一个计数器的值被检索。时间指定为FILETIME。 返回值 如果函数成功，它返回ERROR_SUCCESS。否则，该函数返回一个系统错误代码或一种PDH错误代码。 以下是可能的值。 返回codeDescription PDH_INVALID_HANDLEThe查询处理是无效的。 PDH_NO_DATAThe查询目前还没有任何柜台。 备注 调用此函数时，您要收集查询中的计数器计数器数据。光端机存储原始计数器值为当前和以前的集合。 如果您想检索当前原料计数器的值，调用PdhGetRawCounterValue功能。如果您想计算的计数器值显示的值，调用PdhGetFormattedCounterValue。如果计数器路径中包含一个实例名通配符，而不是调用PdhGetRawCounterArray和PdhGetFormattedCounterArray职能分别。 当PdhCollectQueryDataEx是要求从一个计数器实例唯一的数据，以及计数器实例不存在，该函数返回PDH_NO_DATA。但是，如果从多个计数器数据查询，PdhCollectQueryDataEx可能会返回计数器实例ERROR_SUCCESS即使还不存在。这是因为它不知道如果指定的计数器实例不存在，或是否会存在，但尚未建立。在这种情况下，要求利益的计数器实例每个PdhGetRawCounterValue或PdhGetFormattedCounterValue功能，以确定它们是否存在。 要求： client最低支持Vista server最低支持 Windows Server 2008 HeaderPdh.h LibraryPdh.lib DLLPdh.dll 参见 PdhCollectQueryData PdhGetFormattedCounterValue PdhGetRawCounterValue PdhOpenQuery 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年7月23日 ＝＝英文原文＝＝PdhCollectQueryDataWithTime Function Collects the current raw data value for all counters in the specified query and updates the status code of each counter. Syntax C++ PDH_STATUS PdhCollectQueryDataWithTime( __inout PDH_HQUERY hQuery, __out LONGLONG *pllTimeStamp ); Parameters hQuery [in, out] Handle of the query for which you want to collect data. The PdhOpenQuery function returns this handle. pllTimeStamp [out] Time stamp when the first counter value in the query was retrieved. The time is specified as FILETIME. Return Value If the function succeeds, it returns ERROR_SUCCESS. Otherwise, the function returns a system error code or a PDH error code . The following are possible values. Return codeDescription PDH_INVALID_HANDLEThe query handle is not valid. PDH_NO_DATAThe query does not currently have any counters. Remarks Call this function when you want to collect counter data for the counters in the query. PDH stores the raw counter values for the current and previous collection. If you want to retrieve the current raw counter value, call the PdhGetRawCounterValue function. If you want to compute a displayable value for the counter value, call the PdhGetFormattedCounterValue . If the counter path contains a wildcard for the instance name, instead call the PdhGetRawCounterArray and PdhGetFormattedCounterArray functions, respectively. When PdhCollectQueryDataEx is called for data from one counter instance only, and the counter instance does not exist, the function returns PDH_NO_DATA. However, if data from more than one counter is queried, PdhCollectQueryDataEx may return ERROR_SUCCESS even if one of the counter instances does not yet exist. This is because it is not known if the specified counter instance does not exist, or if it will exist but has not yet been created. In this case, call the PdhGetRawCounterValue or PdhGetFormattedCounterValue function for each of the counter instances of interest to determine whether they exist.
