Sun Java System Web Server 7.0 Update 3 NSAPI Developer's Guide

flush Filter Method

The flush filter method is called when a filter or SAF calls the net_flush function. The flush method should pass any buffered data to the next filter by calling net_write(layer->lower, ...). The flush method is optional, but it should be implemented by any filter that buffers outgoing data.

For more information, see flush() Function in Chapter 6, NSAPI Function and Macro Reference.
