I'm back again.
I could not ignore such a strong suggestion of not using thread. So I am
planning on a single threaded event driven model for my application. I also
plan to use sqlite3_progress_handler() to handle query cancellation.
I compiled SQLite with the flags SQLITE_THREADSAFE=0. Even the

I use both int sqlite3_errcode() and sqlite3_errmsg(). Here is what they
return (I get 3 different types of errors in different runs):
