fsync_file()

void vanedb::detail::fsync_file ( const std::string &  path )

inlinenoexcept

Reopen a file by path, fsync to disk, close. Best-effort durability: silently no-ops if the file cannot be opened.

Caller must close any other writer (e.g. std::ofstream) for the same path before calling — Windows CreateFileA fails on an exclusively-held file.
