I think I can arrange that.
In the mirage code we've settled on using OCaml 'bigarrays' [1]
(wrappers around C arrays) to pass around buffers, represent memory
pages etc. The OCaml standard library has the ability to mmap() stuff
and return a bigarray but there was an unfortunate bug where it assumed
the thing being mmap()ed also supported lseek() [2]. The bug was fixed
in OCaml 4.00.0 so if we're happy to depend on that then we're ready to
roll.
Cheers,
Dave
