tdb questions

[Daniele]

Hi list,
I'm looking for tdb docs and examples. In the wiki there is the sources to download and I'm reading them but I have some questions and I'm sure you can answer.

Which is the difference between using or not mmap? Is it suggested the use of mmap and if not available there is the fallback or are there other things to take in account when making the choice?

From what I know, tdb is a persistent db. The application I'working on would work on a system which can loose power so which would be the best practices to avoid corruptions?

Any help would be greately appreciated.

Regards,
Daniele.
