Looks like there's already a test for this (see the end of test_converttostr).
It doesn't return a string, but returns status DBSTATUS_S_ISNULL.

I think, given that's the case, you should add a comment above the new test,
stating that Windows returns 110, but we're not testing it.  Also remove the
initialization of dst_len before the call, since if we're not testing it there's no
need to initialize it.

Huw.
