Pretty much just implement the functions as documented. One gotcha is that xRandomness is only called once and is only called on the default VFS which makes testing it fun. Another is that xGetLastError is never called so you don't need to implement it. http://www.sqlite.org/cvstrac/tktview?tn=3337 You then need to run queries that exercise all parts of the VFS. If you want some guidance, this is what I use: http://code.google.com/p/apsw/source/browse/apsw/trunk/tests.py#4759 Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkkQssUACgkQmOOfHg372QTuLwCgygTWzPSW3CCHnQONXiEcKXf7 5XEAnR7DYzMf+hvXCORi/I/hpWgWF/t3 =3tEY -----END PGP SIGNATURE----- _______________________________________________ sqlite-users mailing list [email protected] http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
