GetSystemTimes功能
定时信息检索系统。在多处理器系统,返回值是在指定时间在所有的处理器的总和。
参数
lpIdleTime [指出,可选]
一个 FILETIME结构,它接收的时间,该系统已闲置的指针。
lpKernelTime [指出,可选]
一个 FILETIME结构,它接收的时间,该系统花了在内核模式下执行在所有的处理器(包括所有进程的所有线程,指针)。
lpUserTime [指出,可选]
一个 FILETIME结构,它接收的时间,该系统已花了用户模式上执行所有的处理器(包括所有进程的所有线程,指针)。
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。

==英文原文==GetSystemTimes Function
Retrieves system timing information. On a multiprocessor system, the values returned are the sum of the designated times across all processors.
Syntax
C++
BOOL WINAPI GetSystemTimes(
__out_opt LPFILETIME lpIdleTime,
__out_opt LPFILETIME lpKernelTime,
__out_opt LPFILETIME lpUserTime
);
Parameters
lpIdleTime [out, optional]
A pointer to a FILETIME structure that receives the amount of time that the system has been idle.
lpKernelTime [out, optional]
A pointer to a FILETIME structure that receives the amount of time that the system has spent executing in Kernel mode (including all threads in all processes, on all processors).
lpUserTime [out, optional]
A pointer to a FILETIME structure that receives the amount of time that the system has spent executing in User mode (including all threads in all processes, on all processors).
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 compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later. For more information, see Using the Windows Headers .
Requirements
Minimum supported clientWindows Vista, Windows XP with SP1
Minimum supported serverWindows Server 2003
