this contains a very basic vfs implementation; kinda uses internal file
abstraction stuff so a lot can be stripped out and replaced with
fopen/fread/etc...

I haven't read the book, but one thing that may help is not using C
for these. I think it is easier

Given that the book is over four years old and covers to the end of SQLIte3

It looks like a standard POXIS implementation. My guess

You could add VFS creation if you ever do a revised edition (along with a
virtual table example that actually used xBestIndex and xFilter...).

I assume you’ve read the VFS docs: http://www.sqlite.org/vfs.html

we plan to port the SQLite library on an embedded system, which runs on a
platform other than the ones that are supported out of the box (it’s an SMX
based system). For the first step, we don’t need a working mutex subsystem,
because we have no multithreaded environment. The required standa
