Hi,

a possibility to set the offset in a bigarray-mmap file
would be very useful. Either bigarray_map_file should
get 6 parameters or the currpos value from the file
descriptor could be used. The main drawback for my
wish is, that it may breaks existing ocaml programs.

Furthermore a wrapper for getpagesize() is needed
to calculate a valid offset.

Thanks,
Christoph Bauer

(0003927) xleroy (administrator) 2007-02-21 16:19	Feature implemented in 3.10 as an optional argument to the map_file functions. The argument gives the file offset for the beginning of the file data. Arbitrary offsets (not necessarily page-aligned) are supported.
