Subject: [Caml-list] Limits for Bigarray.Array?.map_file

I have to do some work with really huge files
(>1GB). Bigarray.Array1.map_file works fine and very fast for small
and medium sized files, but virtual memory is limited.  (On windows
AFAIK 2GB). Is there a way to specify an offset to the given file
(e.g. with a seek command) to make several Bigarrays of one file?
What is a realistic limit of the size for such a Bigarray?  Are there
known differences between Unix/Windows?

A 64 bit processor is not a solution.

Thanks for any enlightenment,
Christoph Bauer

if w then f a1 false (i +. 2.0) j else f a1 true i (j +. 2.0) in f 2.0 false 2.0 1.0
