That is way beyond my area of competence. I’m not a good C programmer. But there are other people on this list who are. > By the way, is there a possibly way to submit patch to sqlite? Although SQLite is 'open source' it's not your typical open source project. Almost all the code in SQLite was written by a small development team. The team tends to accept development ideas from the outside (e.g. this list) and write the code themselves rather than to accept code written outside the team. This allows them to enforce a consistent programming style and to ensure code is not copied from other projects under licence. In fact it's a problem if you show them your code since they then might be accused of copying it. (Not to accuse you personally of copying code, I'm just layout out the general principle.) There’s also a requirement of usefulness vs. code size. One of SQLite's jealously-guarded advantages is that it's tiny. It has to fit in embedded processors, on phones, and in various hand-held devices with very limited space. SQLite doesn’t add size to the project just because it’s easy, or because someone wrote the code and it works. It adds it because it would be useful to a lot of users. I've had an SQL-conformance change neglected because even though SQLite would conform more closely to SQL it wouldn't allow users to do anything more. If you find your new facility useful then you can use it yourself, by maintaining your own fork. But a minor speed improvement for a single platform, dependent on an OS facility, may not get integrated into the main projects. Sorry if I have disappointed you.
