I believe so. Bot more properly, those are _Unix_ APIs; not every OS has them. (I know very little about Windows, but from what I’ve heard, its filesystem semantics are quite different in some ways.) If you want to know how to lock files on Unix, looking at SQLite is probably not the best thing to do, because SQLite has a lot of other complex things to do when it manages locks. —Jens _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
