I think that the structures are not public. No driver can use this
structures. M$ can change the structures between service packs. IMO it
exsits no reason to use exactly the same structures. In the near future,
I will do some changes. It is necessary to split the segment structure
in one large 'page' table and some short structures for each segment. It
is nearly the same like the control area, the subsections and the
segment. It is also necessary to use only one memory area for a mapped
image section. I need this to implement the executing of low alignment
executables (like device drivers).

We have a 'PFN' database. It is in freelist.c.
