There's no bared pointer after pointer->bytevector or wrapped with
record-type. Anyway, since Guile can't operate pointers directly, so
it's no need to compare with C about 'protect pointer'.

but howto protect your pointer ?
Also, mmap-ed spaces can hardly be GCed, this will introduce extra complexities.
still see no extra necessary in compare to ports.

There has been a lot of talk about the interface, but here's a simple
idea: Post some examples of how you want to use it.
We can all sit around and argue forever and a day about the API, but if
you want it, you probably have some real-word examples in mind and if
you don't, then that's a good rea

And have you considered that you can munmap only some sections, how is
that going to work with your proposed struc
Hello,
Apologies if this is well-known and I just forgot it, but can bytevectors
be read-only? I think we'd need that to handle read-only mmap'ed memory.
(If not, I hope we could allow read-only bytevectors.)
Bytevectors include size, so there's no need to put that in a struct, but
I'm not sure w

hi guys!
A discussion on IRC about adding 'mmap' raised, and I will share some
ideas on this topic:
1. Complex one or simple one?
The simple one is just a simple wrapper taking advantage of (system
foreign).
The complex one is more alike Python's mmap module. Contains a special
type of , and a bun
