Detailed Description

A data handler may be added to a connection.

It is called every time data is enqueued or printed to the connection. The buffer is passed through all installed data handlers which might replace the buffer by a different buffer. If a data handler returns NULL no data is printed or enqueued to the connection and the handler is uninstalled and released.
