GetProcessTimes (Compact 2013)


This function retrieves the timing information for the specified process.

BOOL GetProcessTimes(
   HANDLE hProcess,
   LPFILETIME lpCreationTime,
   LPFILETIME lpExitTime,
   LPFILETIME lpKernelTime,
   LPFILETIME lpUserTime


[in] Handle to the process.


[out] Pointer to a FILETIME structure that receives the creation time of the process.


[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.


[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.

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.

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.
