The `DbMpoolFile::sync()` method writes all modified pages associated with the DbMpoolFile back to the source file. If any of the modified pages are pinned (that is, currently in use), `DbMpoolFile::sync()` will ignore them.

The `DbMpoolFile::sync()` method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
