+ * Name      : BOOL GetProcessTimes
+ * Purpose   : The GetProcessTimes function obtains timing information about a specified process.
+ * Parameters: HANDLE     hProcess       specifies the process of interest
+ *             LPFILETIME lpCreationTime when the process was created
+ *             LPFILETIME lpExitTime     when the process exited
+ *             LPFILETIME lpKernelTime   time the process has spent in kernel mode
+ *             LPFILETIME lpUserTime     time the process has spent in user mode
+ * Variables :
+ * Result    : TRUE / FALSE
+ * Remark    :
+ * Status    : UNTESTED STUB
+ *
+ * Author    : Patrick Haller [Mon, 1998/06/15 08:00]
