TIdIOHandler.WriteBufferClose Method

Disables uses write buffering for the IOHandler connection.

procedure WriteBufferClose; virtual;

WriteBufferClose is a virtual procedure used to disable use of buffering when writing data to the connection for the IOHandler. 

WriteBufferClose calls WriteBufferFlush to ensure that any existing data in WriteBuffer is written to the IOHandler connection. WriteBufferClose also frees the WriteBuffer. 

Use WriteBufferOpen to enable use of the WriteBuffer for data written to the IOHandler connection.
