If any file modifications are still in the cache, they are written to disk. zFlush blocks until the file flush is complete and then returns to the caller. zFlush should not be called as part of a transaction because the transaction could be aborted and might have extra work to do. The transaction automatically takes care of any flushing that needs to be done.
