Does anybody know if there's a system call or something that allows a
chunk of physical memory (I'm thinking a block of dpm located on a PCI
board) to be mapped into the addressing space of a user program, so
it's directly addressable?
I suppose the alternative would be to have a device driver or a dll
copy blocks of stuff between the PCI bus and the user space, but
that's clumsy.
