BOOL GetProcessTimes(
HANDLE hProcess,
LPFILETIME lpCreationTime,
LPFILETIME lpExitTime,
LPFILETIME lpKernelTime,
LPFILETIME lpUserTime
);Parameters
hProcess
[in] Handle to the process whose timing information is sought. This handle must be created with the PROCESS_QUERY_INFORMATION access right. For more information, see Process Security and Access Rights.
lpCreationTime
[out] Pointer to a FILETIME structure that receives the creation time of the process.
lpExitTime
[out] Pointer to a FILETIME structure that receives the exit time of the process. If the process has not exited, the content of this structure is undefined.
lpKernelTime
[out] Pointer to a FILETIME structure that receives the amount of time that the process has executed in kernel mode. The time that each of the threads of the process has executed in kernel mode is determined, and then all of those times are summed together to obtain this value.
lpUserTime
[out] Pointer to a FILETIME structure that receives the amount of time that the process has executed in user mode. The time that each of the threads of the process has executed in user mode is determined, and then all of those times are summed together to obtain this value.
Return Values
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.Res
All times are expressed using FILETIME data structures. Such a structure contains two 32-bit values that combine to form a 64-bit count of 100-nanosecond time units.Process creation and exit times are points in time expressed as the amount of time that has elapsed since midnight on January 1, 1601 at Greenwich, England. There are several functions that an application can use to convert such values to more generally useful forms.Process kernel mode and user mode times are amounts of time. For example, if a process has spent one second in kernel mode, this function will fill the FILETIME structure specified by lpKernelTime with a 64-bit value of ten million. That is the number of 100-nanosecond units in one second.Requirements
Client Requires Windows XP, Windows 2000 Professional, or Windows NT Workstation 3.5 and later.
Server Requires Windows Server 2003, Windows 2000 Server, or Windows NT Server 3.5 and later.
Header Declared in Winbase.h; include Windows.h.
Library Link to Kernel32.lib.
DLL Requires Kernel32.dll.
DWORD dwStart = GetTickCount();
结尾处:
DWORD dwEnd = GetTickCount();
DWORD dwTime = dwEnd-dwStart;
CString s;
s.Format(_T("function : %s\nuseTime = %d : %d : %d : %d"),
funcName,
dwTime/(1000*60*60),
(dwTime%(1000*60*60))/(1000*60),
((dwTime%(1000*60*60))%(1000*60))/1000,
((dwTime%(1000*60*60))%(1000*60))%1000);
得到的s就是进程运行的时间
