/*

The Buffered Socket Writer Stream is an output
stream  which knows how to write to a BSD type socket. It is part
of the Transport interface and may be registered
as part of a Transport Object. The application
can initialize this stream together with the
HTReader stream, for example. In the
default initialization module, you can find the
HTTransportInit() function which sets up this stream as a default
transport for handling unbuffered socket write operations.

The difference from the unbuffered write stream
is that this stream lets you write characters without causing a
write system call every time. The data is first written into
a buffer. Data is written to the transport only when the buffer is full,
or when the stream is flushed.

This module is implemented by HTBufWrt.c, and it
is a part of the W3C Sample Code
Library.

  Default Output Buffering
.

In order to optimize reading a channel, we bind a buffer to each channel
object. The size of this buffer is a compromise between speed and memory.
By default, we have chosen a value frequently used in TCP connections. In
the stream creation method you can pass any other buffer size. In the case
of 0, we take the default size.
