Subject: How can I use grant table in domainU?

Can applications runs in domainU use grant table?
I found a way in the document(/docs/misc/grant-tables.txt), using function gnttab_grant_foreign_access . But, this fucntion is defined in domainU kernel, for example, in my installation, it's in /linux-2.6.18-xen.hg/include/xen/gnttab.h.
Then how can I call this function in my own application?
If I wants to write a simple program(program1) runs in domainA, to map a frame to domainB, in which another simple program(program2) is running, then program2 can read the information program1 sent to domainB, what should I do?
thanks.
