求一个得到CPU占用率的函数
搜索了很久，也没有找到能得到CPU占用率的函数，很多都是WMI的，看到P版说有2NtQuerySystemInformation和PDH的方法，但是都不知道怎样实现。有谁能够提供这2个方法实现的函数不胜感激啊！ 这2天一直在看P版的Pdh.au3里面的例子，可是还是没有看懂，希望P版能够提供一个得到CPU使用率和内存使用率的例子。 #include <StaticConstants.au3>#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>

多谢了，可是我没有看懂，我太菜了，呵呵。
能不够帮我改改，比如当前我看见的任务管理器里CPU使用时20%，我调用_CPUCalc()函数就能得到返回值20或者20%，非常感谢帮组啊。
