By "no-op" I meant that it's not doing anything in a broader context,
i.e. it's not decreasing the length integer used by the caller function.
I've been pointed to the compiler warning (see bug topic of
http://bugs.php.net/bug.php?id=48185) and propery fixed it. When I ran
the test suite lots of test cases were failing because the output was
truncated.
I think that this by itself is the proof that sqlite3_column_bytes() is
not including the NULL terminator. To be sure I've also checked
sqlite3.h and couldn't find any reference to that behaviour.
The comment is wrong and the code is not doing what the comment tells,
so I thought that a clean up was required, both for consistency and to
fix the compiler warning.
Cheers
