There is no public API. If you use the amalgamation then you can add
code to dig it out of the SQLite internals (a hash table amongst other
things). Look for functionSearch and sqlite3FindFunction

Hi,
I have an application running on Windows CE4.1 PDAs with SD cards.
Sometimes I have errors executing commands on database that are:
11-database disk image is malformed
This happens for example on table MSTBP executing Delete From MSTBP.
Or inserting into it.
The strange thing is, that

Hi,
my java application uses a 80Mb reference database (read-only) that needs to be
consulted app. 4M times during a batch run. I would like to use the in-memory
capabilities of sqlite3 to improve the performance of my app.
In order to do so, I setup a Connection to the -in-memory- sqlite
A position is politics, not science. Warnings about the use of
threads are based on science, and advise you to avoid them if possible
for your own protection.
I see ill conceived programs using threads which go to complex
synchronization to achieve the equivalent of single stream execution
I'm curious: with all these warnings based on science how would you
implement application similar to apache web-server (forget about cgis
- just plain HTML) or something like database server? I understand
that you always can write something like cgi application which run on
every web-page hit but

For example I have one database connection and 2 database statement handle

The danger with threading is in concurrent access to data. Apache has
several different modes of operation
So you don't even try to argue about database-servers-like
applications? Apache maybe indeed not very good example because of
good degree of independence between threads, though I think in some
cases caching across different connections and thus across different
threads could be useful.

With all due respect, science itself is a set of

official doctrine after appropriate study. Saying A 'position' is

So, you suggest I should build a commercial desktop application (for
processing print-industry files and presenting them in a UI) in such
a way that it spawns multiple processes and communicates with them via

Why would I want to go to that level of complexity

I understand that. That's why concurrent access should be made very
wisely. But if this concurrent access is to some cache which allows to

I can't agree that such a thing would be a good approach in a

Would you please shed some light on this?

Err, you don't have seventy five executables and expect the user to
