| 释义 | QueryProcessCycleTime 语法： C++ BOOL WINAPI QueryProcessCycleTime( __in HANDLE ProcessHandle, __out PULONG64 CycleTime ); QueryProcessCycleTime功能 检索的指定进程的所有线程的周期时间的总和。 参数 ProcessHandle [in] 句柄的进程。句柄必须有PROCESS_QUERY_INFORMATION或PROCESS_QUERY_LIMITED_INFORMATION访问权限。有关更多信息，请参见过程的安全性和访问权限。 CycleTime [out] The number of CPU clock cycles used by the threads of the process.此值既包括用户模式和内核模式下的周期。 返回值 如果函数成功，返回值为非零。 如果函数失败，返回值是零。为了获得更多错误信息，调用GetLastError。 备注 枚举系统中的进程，使用EnumProcesses函数。 要编译的应用程序使用此功能，定义_WIN32_WINNT为0x0600或更高版本。 要求： client最低支持Vista server最低支持 Windows Server 2008 HeaderWinbase.h(头文件：winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 QueryIdleProcessorCycleTime QueryThreadCycleTime 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＝＝QueryProcessCycleTime Function Retrieves the sum of the cycle time of all threads of the specified process. Syntax C++ BOOL WINAPI QueryProcessCycleTime( __in HANDLE ProcessHandle, __out PULONG64 CycleTime ); Parameters ProcessHandle [in] A handle to the process. The handle must have the PROCESS_QUERY_INFORMATION or PROCESS_QUERY_LIMITED_INFORMATION access right. For more information, see Process Security and Access Rights . CycleTime [out] The number of CPU clock cycles used by the threads of the process. This value includes cycles spent in both user mode and kernel mode. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks To enumerate the processes in the system, use the EnumProcesses function. To compile an application that uses this function, define _WIN32_WINNT as 0x0600 or later.
