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.

#define OUTPUT_BUFFER_SIZE 1024
