Subject: question about mapping memory from Dom0 to domU

Hi:
I wanna write code about sharing memory between dom0 and domU, and I decide to use void *xc_map_foreign_range(int xc_handle, unint32_t dom, int size, int port, unsigned long mfn) (this is a function in xenctl.h).
My question is :
If I wanna map a range of memory in dom0 to domU, how can I get the value of mfn? and I do not know the port here.
Can anybody help me ?
Thanks .
Danius Wu
