I have an SQLite database which I work in memory (:MEMORY) and I

Is there a way to do it without writing it to disk and reading the

Command ATTACH works good to get and write from disk or to work
directly in
memory but I cannot get the database itself (buffer) from memory.
I would also need some way to get the database from the binary
string of it.
This is because I trasmit the database via HTTP (I encrypt the string
before). Now I'm using XML, but as it is becoming complex I´d like
to put
SQLite.
Of course its a small string (10Kb).
I don't even know whether there's a binary in-memory image for
the :memory: database, but you could always dump the entire database
(as you'd do with the '.dump' command in the shell), send that over
and import it on the other end.
The code to dump the database is avaiable in shell.c as well as the
code to import a database, so you can easily integrate this into your
own executable...
For a small database, going through the dump-import process shouldn't
be too much of a performance hit (plus it makes you independent of
the sqlite version/implementation used on the other end).
