What is the right procedure to memory-map a file into a bigarray?
Thanks, Joel

What do you mean the functions do not work ?

Foot in mouth. I looked in the Bigarray module instead of ArrayX.
FYI, there's a bug that causes OCaml to run out of memory after
repeated mmaps of bigarray, logged by Markus Mottl back in 2006. It's
marked as "acknowledged" so I gather it's still not fixed.
Is this the case?
Thanks, Joel

Bigarray.M.map_file, for M = Genarray, Array1, Array2, or Array3
