Yet there are quite a few of them on CPAN.
I recall somebody even made a mmap module that works on Win32; the author was here and on the chatterbox while he was working on it, but I don't remember what user that was.
Maybe it was IPC::Mmap? Ah, no, it must have been Win32::MMF, the name rings a bell. Well, both look like reasonable approaches to me, and both have gotten recent updates, which is a promise it'll most likely still work well. But don't discard the other candidates just yet.
From the top of the thread:
I have a hash (with about 20-25 keys) with very long bit strings as values (1-2MB) that I would like to share directly (readonly) in memory.
That looks like an acceptably small number of keys, so the most sane approach to me seem to make a separate mmapped file per hash item. If the keys form a fixed set, you don't even actually have to share the list of names. | [reply] |
