DbMpoolFile::sync();

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.
