fflush() is one of the standard C routines for file manipulation. It causes the currently pending data, if any, to be 'flushed' (written) to disk. When you call fwrite(), the data may not be written to disk but may be storead in an internal buffer in order to speed up successive writes. fflush() writes the buffer to disk if it has unwritten data in it.

It's use is not required, but useful if you want to be absolutely sure that some set of writes has completed before, say, responding to a request. That way, should the machine crash your data is likely to be safe on disk.
