in the documentation: "Appropriate Uses For SQLite" it
says:
"it is often easier and quicker to load the data into
an in-memory SQLite database and use queries with

I understand you are supposed to open a new sqlite3 connection for
every thread that needs access, but- would it be safe to wrap access
to the database with a mutex? I've got code that needs to insert at
random times (sometimes many times per sec) and select once per sec in
another thread. The

Ok I have skimmed the archives and even though people have had similar
problems there solution all point to using '' as an escape instead of
'\. However that doesnt solve my problem. I am writting a mp3player

Agreed. In fact I use cgic in either C or C++, since it's easy to use.
The licensing is agreeable too, since even a commercial license is very
inexpensive.

It will do locks but you can lock/unlock really fast.

You are opening yourself to such problems only if you do something rash
like try to write your own CGI
Ok thanks for responding...
That was my understanding but I was wondering why it only returned 1 Row in
*pnRow. I've figured it out now (I think). The first row contains the column
name but does not count as a result. Hence the 1 row that is referred to in
*pnRow returned from sqlite3_get_table()

Yes, but modern C compilers generate code that's 99% as good as
a human would write. I've tried to write better code in assembler
than the compiler does. I've managed it, but's it's pretty hard.
If you profile your code you generally find that

FWIW, the CVSTrac program used for bug tracking on www.sqlite.org
is a C program that runs as CGI and uses SQLite as its database
backend.

I am using version 3.0.8 of sqlite.
In the course of trying to track down a strange error in my application
where I very infrequently get a database is locked error (even though my
busy timeout is set to some insanely large number, like a billion seconds),
I was looking through the code is
