how to get memory's physical address in user-mode?

[LongdaFeng at viatech.com.cn]

Dear friends:

         I am sorry for asking this question here? 

But it trouble me much, and thank you very much whatever you suggest!!!!!

 

         The question is as down:

         I malloc 16k memory in user mode

         (1) how to make this memory reserved, it means that it can’t be swap out 

         (2) how to get this memory’s physical address

 

         I know the method implement this in kernel mode, but I don’t know how to do this in user mode.

 

         Thank you very much!!!

 

Best regards

Longda Feng
