Sorry, what do you mean on question 2?
Can I use the buffered fopen family functions or not?
You probably can. I don't think you should though.

I'm studying the demovfs listed on http://www.sqlite.org/vfs.html.
I've got a few questions:
1. By reading the comments, it seems that file read/write operations
must be buffered if it is a journal file. Is this required by sqlite
design?
No. Not required.
2. The demo uses nonbuffered open/read/write function to talk with
OS. Can I use the buffered fopen/fread/fwrite functions and thus I
don't bother with buffering management?
The user-space buffering seems quite likely to introduce confusing
bugs. Probably easiest not to.
