术语 | getperformanceinfo |
释义 | GetPerformanceInfo 语法: C++ BOOL WINAPI GetPerformanceInfo( __out PPERFORMANCE_INFORMATION pPerformanceInformation, __in DWORD cb ); GetPerformanceInfo功能 检索性能值的PERFORMANCE_INFORMATION结构中。 参数 pPerformanceInformation [out] 一个 PERFORMANCE_INFORMATION结构,接收性能信息的指针。 文件 [in] 该PERFORMANCE_INFORMATION结构的大小,以字节为单位。 返回值 如果函数成功,返回值为TRUE。如果函数失败,返回值为FALSE。为了获得更多错误信息,调用GetLastError。 备注 与PSAPI版本的Windows 7和Windows Server 2008 R2的2起,这个函数被定义为K32GetPerformanceInfo在Psapi.h和Kernel32.lib和Kernel32.dll出口。但是,您应该始终作为GetPerformanceInfo调用这个函数。为了确保对程序将运行在Windows的早期版本的符号的正确决议,添加Psapi.lib到TARGETLIBS宏和编译程序与- DPSAPI_VERSION = 1。 要求: 最低支持client-Windows XP 最低支持serverWindows服务器2003 HeaderPsapi.h LibraryKernel32.lib在Windows 7和Windows Server 2008 R2的Psapi.lib在Windows Server 2008,Windows Vista中的Windows Server 2003,和Windows XP/2000 DLLKernel32.dll在Windows 7和Windows Server 2008 R2的Psapi.dll在Windows Server 2008,Windows Vista中的Windows Server 2003,和Windows XP/2000 参见 内存性能信息 PERFORMANCE_INFORMATION PSAPI函数 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8月27日 ==英文原文==GetPerformanceInfo Function Retrieves the performance values contained in the PERFORMANCE_INFORMATION structure. Syntax C++ BOOL WINAPI GetPerformanceInfo( __out PPERFORMANCE_INFORMATION pPerformanceInformation, __in DWORD cb ); Parameters pPerformanceInformation [out] A pointer to a PERFORMANCE_INFORMATION structure that receives the performance information. cb [in] The size of the PERFORMANCE_INFORMATION structure, in bytes. Return Value If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError . Remarks Starting with PSAPI version 2 for Windows 7 and Windows Server 2008 R2, this function is defined as K32GetPerformanceInfo in Psapi.h and exported in Kernel32.lib and Kernel32.dll. However, you should always call this function as GetPerformanceInfo. To ensure correct resolution of symbols for programs that will run on earlier versions of Windows, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1.
