...A database connection handle is usually returned in *ppDb, even if
an error occurs. The only exception is that if SQLite is unable to
allocate memory to hold the sqlite3 object, a NULL will be written
into *ppDb instead of a pointer to the sqlite3 object. If the
database is opened (and/or created) successfully, then SQLITE_OK
is returned. Otherwise an error code is returned. The
sqlite3_errmsg() or sqlite3_errmsg16() routines can be used to
obtain an English language description of the error following a
failure of any of the sqlite3_open() routines.
